Arguments for strengthening the doctrine to make claims easier to pursue are common. See, e.g., Richard H. McAdams, Race and Selective Prosecution: Discovering the Pitfalls of Armstrong, 73 Chi.-Kent L. Rev. 605, 606 (1998) (discussing use of the equal protection doctrine but challenging current precedent). 94 Grand juries remain a fixture in the federal system and in roughly half the states. See Sara Sun Beale et al., Grand Jury Law and Practice § 1:5 (2d ed. 2017) (describing grand jury status and rules in states and noting states that have partially or wholly abolished grand juries); Andrew D. Leipold, Why Grand Juries Do Not (and Cannot) Protect the Accused, 80 Cornell L. Rev. 260, 274-75 (1995) (noting difficulty of getting data on grand jury screening and offering reasons why grand juries rarely reject requests for indictments). To extend the comparison, public officials (judges) have a long track record of doing the same task that trial and grand juries do. That available substitute did not lead to calls for juries' abolition. Yet the availability of public prosecutors as replacements led to the U.S. jurisdictions to abolish private prosecutors.

Finally, another institution responds to some of the same underenforcement problems that private prosecution and judicial review could address - redundant prosecution authority in a federal system. C. Federalism Safeguards on Prosecutorial Discretion The scope of the U.S. federal criminal code expanded vastly in the twentieth century, as did the federal government's institutional capacity to enforce that code and its regulatory authority more generally. The result has been a distinctive form of criminal justice federalism: federal enforcement authority wholly overlaps the territorial scope of state criminal law, and the federal code substantially overlaps much of what is covered in state criminal codes. The resulting structure of redundant federal-state authority has evolved into a means - unusual even among federal nation-states - to second-guess and effectively trump state prosecutors' declination decisions without empowering courts or private parties. No other nation built on a federal model incorporates nearly [*885] the same degree of redundancy between state and federal justice systems. 131 The more common model of criminal justice federalism is found in Canada and Germany: each has a single national criminal code that is administered by separate state-level prosecution agencies and court systems. 132 Other federal states follow the U.S. model and have separate criminal codes, prosecution agencies, and court systems in each state as well as for the federal government. Australia follows this model, but the scope and jurisdiction of Australian federal criminal law is much more limited than is U.S. federal law; federal crimes are largely confined to offenses that implicate distinct federal interests - it is probably closer to U.S. federal criminal law in 1910 than 2010. The result is that in Australia federal criminal law enforcement overlaps much less with state criminal law. 133 The broad redundancy provided by U.S. federalism enables federal prosecutors to serve as checks on underenforcement by state prosecutors, at least for some large and important categories [*886] of crime. In effect, federal prosecutors can review the declination decisions of state prosecutors - as well as the adequacy and success of their prosecutions - and then decide whether to file federal charges in cases that their state counterparts declined to pursue, charged too leniently, or in which they failed to win a conviction or sufficiently harsh sanctions. (In theory state prosecutors conduct the same oversight over much of 95 See George Fisher, The Jury's Rise as Lie Detector, 107 Yale L.J. 575, 671-96 (1997) (discussing the impact of racial policies in post-Civil War jury and court processes). 96 I am aware of no historical research on African American private prosecutors, and I have found no evidence of any in case law or general accounts of private prosecutions. 97 See, e.g., Fisher, supra note 95, at 684 n.514 ("Denial to the freedman of the power to testify in court against the white man … strikes not at a mere civil franchise, but at a natural right - the right of protecting life and property. When a white man may take a freedman's life or property with impunity, if no other white men be present, the freedman has no security for either." (quoting The Progress of Reconstruction, N.Y. Times, Oct. 3, 1865, at 4)). 98 When Southern states were compelled to grant African American citizens litigation rights, they imposed strict conditions, permitting African Americans the right to testify only when the crime victim (or the opposing civil litigant) was African American. Id. at 684. Those limitations likewise restricted African Americans' private prosecution authority, although in many places racial customs, backed by the prospect of racial violence, was probably discouragement enough. See generally Douglas A. Blackmon, Slavery by Another Name: The Re- Enslavement of Black Americans from the Civil War to World War II (2008) (discussing history of African Americans' distrust of America's judicial system); Nicholas Lemann, Redemption: The Last Battle of the Civil War (2007) (exploring incidents after the Civil War and the impact on politics during the Reconstruction Era). 99 Michael J. Klarman, From Jim Crow to Civil Rights: The Supreme Court and the Struggle for Racial Equality 49-51 (2004). Northern states were not models of race-blind democracy. Connecticut voters in 1865 rejected a proposal to enfranchise African American citizens in their state. Fisher, supra note 95, at 685. 100 See Council Directive 2012/29, art. 11, 2012 O.J. (L 315) 57 (EC) (EU), http://eur-lex.europa.eu/legalcontent/EN/TXT/?uri=CELEX:32012L0029 (requiring member states to give crime victims means to challenge non-prosecution decisions, either through private prosecution or a right to review). 101 See FRA Report, supra note 72 (summarizing policies of EU member states and noting that only Cyprus and Malta provide victims neither right). DAVID SCHOEN 103 Minn. L. Rev. 844, *886 Page 21 of 42 federal enforcement practice, but this is less common.) 134 State prosecutors' decisions, at least for certain categories of serious wrongdoing, face de facto review by federal executive officials. Or so the law for a century has permitted. The constitutional double jeopardy doctrine since at least 1922 has recognized the "dual sovereignty" of state and federal governments. Notwithstanding the guarantee that no person shall "be subject for the same offence to be twice put in jeopardy," the Double Jeopardy Clause has been understood not to preclude federal prosecutors' power to charge a person who has previously been prosecuted by state officials for the same criminal conduct, and federal prosecutions likewise do not limit subsequent state enforcement efforts. 135 By granting certiorari in United States v. Gamble this term, 136 the U.S. Supreme Court is set to revisit this doctrine, which provides the foundation for the federalism-based check on underenforcement. Federal prosecutors do not attempt to keep an eye on all state prosecution decisions and practices, and federal criminal [*887] law is not fully coextensive with state criminal law; significant gaps are discussed in the next Part. But the substantive redundancy is considerable. For some areas of dual authority - such as drug crimes, fraud, child pornography, and human trafficking - federal and state agencies often coordinate investigative efforts and divide up prosecution responsibilities. But federal Justice Department policy to exercise oversight of state enforcement practices in certain categories of crime is deliberate and formalized. Notable examples include state and local government corruption, excessive use of force and other wrongdoing by police, and other criminal civil rights violations. 137 Especially in these areas, federal prosecutors assess whether to file their own charges in cases in which their state counterparts declined to charge, charged too leniently, or in which they failed to win appropriate convictions. Federal prosecution in the wake of state declination is hardly the norm - it should not be, if state prosecutors decline cases for the right reasons 138 - but federal officials do remedy meaningful enforcement gaps left by state prosecutors. 139 Functionally, this inter-governmental model of review resembles intra-agency administrative review with greater independence between initial decision makers and subsequent reviewers. Oversight of state prosecutors rests with the policy [*888] priorities of federal executive branch officials. The Justice Department has well-established written guidelines for much of this oversight activity, although they are not formally binding. 140 Although the Justice Department bureaucracy has a stronger 102 On Scotland, see Victims and Witnesses (Scotland) Act 2014, (ASP 1) § 4 ("The Lord Advocate must make and publish rules about the process for reviewing, on the request of a person who is or appears to be a victim in relation to an offence, a decision of the prosecutor not to prosecute a person for the offence."); Crown Office & Procurator Fiscal Serv., Lord Advocate's Rules: Review of a Decision Not to Prosecute - Section 4 of the Victims and Witnesses (Scotland) Act 2014, at 5 (2015), http://www.copfs.gov.uk/images/Documents/Victims_and_Witnesses/Lord%20Avocates%20Rules%20-% 20June%2015%20v2.pdf.

Rev. 844, *888 Page 22 of 42 institutional culture of professionalism than many state prosecutor offices, departmental policies and priorities can change substantially with presidential administrations - as they have recently. 141 Nonetheless, this federalism-based model of prosecutorial oversight has an advantage shared by the administrative review schemes within single prosecution agencies. In both settings, those with review power are prosecutors who should have greater institutional competence and legitimacy to second-guess other prosecutors' charging decisions, and consequently less inclination than courts to defer to prosecutorial judgments. This federalist model of enforcement redundancy did not evolve from earlier common law institutional arrangements, like private prosecution, nor from the modern victims' rights movement, like judicial and administrative review of decisions not to prosecute. Federal criminal law enforcement expanded for several reasons, but behind many of those reasons is a common purpose: to remedy glaring patterns of underenforcement by the states. For example, federal law and institutional capacity (such as the advent of the Federal Bureau of Investigation) expanded in response to states' inability to confront adequately the rise of interstate violence and drug crimes (as well as, for a time, prohibition on alcohol manufacture and distribution). 142 Federal law [*889] took on the primary role in combatting local government corruption - including police corruption and excessive uses of force - which local prosecution agencies often lacked the ability, or political independence, to confront. 143 And federal law has long attempted to fill the gap when racially biased local police, prosecutors, and juries declined to arrest, prosecute, or convict suspects - especially white ones - who victimized black citizens. 144 In sum, the redundant enforcement 104 Strafprozebetaordnung [StPO] [Code of Criminal Procedure], §§152, 160, 170, translation at https://www.gesetze-iminternet.de/englisch_ stpo/englisch_stpo.html (Ger.)

Rev. 844, *889 Page 23 of 42 authority developed as part of the modern model U.S. federalism has much in common, in functional terms, with private prosecution and review of prosecutorial declination decisions. All are mechanisms to guard against unjustified nonenforcement, or underenforcement, by jurisdictions' primary prosecution agencies. The next Part examines the relative strengths of these alternatives. III. PROS AND CONS OF FEDERALISM-BASED ENFORCEMENT REDUNDANCY A. Comparative Limits of Enforcement-Oversight Strategies Each of the institutional approaches to reducing underenforcement of criminal law by public prosecutors has comparative strengths and weaknesses. All three share the common virtue of being a means to reduce instances of bias, favoritism, or other misjudgments that result in unjustified nonenforcement. All three enable outside reevaluation of declination decisions. Private prosecution empowers motivated private parties - crime victims - to initiate the challenge to a public prosecutor's decision not to charge by filing charges themselves. The same is true in jurisdictions that subject declination decisions to formal administrative or judicial review; victims trigger that process by petitioning for an independent evaluation. Both of those practices harness the motivations of interested private parties to, in effect, screen which declination decisions should be subject to reassessment, although private prosecution poses a significant cost barrier for victims who want to take advantage of it. At the same time, both of these practices give public officials the final [*890] word on whether a prosecution (public or private) will proceed. The federalism route to prosecutorial oversight, by contrast, gives private parties no formal role, although victims can file complaints and lobby federal prosecutors just as they can with local police and prosecutors for any alleged crime. Put differently, federal prosecution as check on state underenforcement rests more directly on the initiative, diligence, and judgment of federal prosecutors than private victims. In some areas, federal commitment is significant. 145 But it also varies with the policy priorities of presidential administrations, which can vary considerably in their commitment to fighting certain kinds of crimes and to federal oversight of state criminal justice administration. 146 106 The U.K. is scheduled to leave the European Union in 2019.

The percentage of prosecution decisions challenged in this way has been well below one percent - 0.13% in 2016-17, and 0.17% in 2014-15 - which suggests the administrative burden is manageable. See id. 109 See Balderstone v. R (1983), 23 Man. R. (2d) 125, at para. 28 (Can. Man. C.A.)

That a judge must not do."). 110 Decisions to discontinue a prosecution after charging get similar scrutiny.

England created its prosecution agency, the Crown Prosecution Service, only in 1985. See Prosecution Offences Act 1985, c. 23, § 1 (Eng. and Wales); Andrew Ashworth & Mike Redmayne, The Criminal Process 222-23 (4th ed. 2010). The Director of Public Prosecutions was created in 1879 but did not handle most prosecutions until the creation of the Crown Prosecution Service. In the intervening century, police came to dominate filing of criminal charges, supplemented by private prosecutions, a system that eventually was viewed as providing insufficient supervision of charging decisions by police. See Williams, supra note 78. DAVID SCHOEN 103 Minn. L. Rev. 844, *890 Page 24 of 42 But that distinction has an upside: private prosecution and judicial review do not work in cases in which there is no direct victim - or in which private parties do not realize they have been victimized, as in some cases of large-scale corporate or government fraud, or in some cases of child pornography. 147 Federal prosecutors, however, take on just such cases as a core part of their enforcement agenda. 148 On the other hand, federal oversight is limited in other important respects: federal criminal enforcement authority is not fully coextensive with state criminal law; notably, for example, it provides effectively no enforcement redundancy for ordinary domestic violence, rape, and other sexual assault offenses. 149 [*891] B. Three Kinds of Offenses: Corruption, Police Violence, Sexual Assault Consider the efficacy for these oversight options with respect three types of offenses: local fraud or corruption, excessive use of force and other wrongdoing by local law enforcement officers, and sexual assaults. These three classes of offenses have in common that they have proven to be especially vulnerable to underenforcement. At the same time, the differences in how U.S. criminal justice institutions have responded to underenforcement in each area highlight the efficacy and limits of the federalism-based enforcement redundancy compared to the alternatives - both those U.S. jurisdictions reject (private prosecution and judicial review) and a fourth, unique strategy they embrace: politically accountable prosecutors. 1. Public Corruption Corrupt conduct by government officials is a category of wrongdoing especially likely to suffer from underenforcement, for obvious reasons: we depend on one set of public officials, prosecutors and investigative agents, to stop wrongdoing by other public officials - as well as by colleagues within their own ranks. Professional and even personal relationships often exist between these groups of public officials. Even when the boundaries between lawful and unlawful conduct are clear and law 112 R (Da Silva) v.

The European Convention on Human Rights may impose affirmative obligations on member states that certain instances require prosecutions, or that more generally require a state to maintain a criminal justice system that provides sufficient protection to citizens. English courts found that their established standards of review of noncharging decisions, based in domestic law, have been held sufficient to meet any such obligation. See R (FB) v. DPP [2009] EWHC (Admin.) 106,[2009] Crim. App. 38, at P 64 (Eng. and Wales) (discussing state obligations under Articles 2 and 3); see also R v. Killick [2011] EWCA (Crim.) 1608, [2012] 1 Crim. App. 10 at [48] (confirming victims' right to review). Judges may require disclosure of internal prosecution documents, but they assess the lawfulness of nonprosecution without examining the underlying evidence. See R (Da Silva) v. DPP [2006] EWHC (Admin) 3204 [24] (Eng. and Wales) (noting use of redacted investigative report and case notes from CPS but disavowing evaluation of evidence). 113 See R v. DPP [2001] QB 330 at 337 (Eng. and Wales); R v. Metro. Police Commr. [1958] 2 QB 118, at 123-25 (Eng. and Wales); Ashworth & Redmayne, supra note 111, at 221-22. Decisions by U.S. courts give no special solicitude to instances of nonprosecution in the wake of injuries or deaths caused by prison guards or other law enforcement officials. See, e.g., Leeke v. Timmerman, 454 U.S. 84, 85-87 (1981) (rejecting state prison inmates' federal civil claim alleging bad faith by state officials to block issuance of arrest warrants against guards on allegations of unnecessary beatings during prison uprising); Inmates of Attica Corr. Facility v. Rockefeller, 477 F.2d 375, 382-83 (2d Cir. 1973) (rejecting request, on behalf of inmates injured or killed by state prison guards in the wake of a prison riot, that federal courts compel state and federal prosecutors to charge guards, reaffirming that prosecutorial discretion is immune to judicial review). To facilitate review, English prosecutors in some circumstances must provide public reasons for choosing not to file charges. See Jordan v. United Kingdom (No. 2) [2003] 37 Eur. Ct. H.R. 52 PP 82-86, 122-23, 142-45 (holding that under article 2 of the European Convention on Human Rights prosecutors should give reasons explaining a decision not to bring criminal charges after an investigation into a death caused by police shootings); see also R v. DPP [2001] QB 330, at 347 (Lord Bingham, CJ) (Eng. and Wales) ("In the absence of compelling grounds for not giving reasons, we would expect the Director to give reasons in such a case [of non-prosecution]: to meet the reasonable expectation of interested parties that either a prosecution will follow or a reasonable explanation for not prosecuting be given … ."); EU Council Directive 2012/29, supra note 100, art. 6, at 67 (requiring explanations to victims that can be subjected to review). Irish victim rights laws that took effect in 2015 now require prosecutors to provide reasons to victims for declining to prosecute. See Mark Hilliard, New Laws on Rights of DAVID SCHOEN 103 Minn. L. Rev. 844, *891 Page 25 of 42 enforcement can learn of misconduct done mostly in secret, political or personal incentives for enforcement officials that discourage zealous enforcement can exist for enforcement officials in the same jurisdiction - perhaps enmeshed in the same political networks. In short, underenforcement in this realm follows more from favoritism toward offenders than the biases against victim groups or types of offenses. "Corruption" is a notoriously hard concept to define, 150 but that difficulty is actually somewhat useful for present purposes. Some of what constitutes public corruption is relatively clearly [*892] defined in positive law. Easy cases involve straightforward property theft or embezzlement, quid pro quo bribery, and extortion. 151 Statutes also make clear at least some cases of illegal gratuities and breaches of regulations that govern activities such as campaign finance. 152 More ambiguous or marginal cases of alleged corruption, however, illustrate the federal government's ambitious commitment to enforcing broad interpretations of federal anti-corruption laws to conduct of state and local officials. That enforcement track record demonstrates the strong commitment to enforcement redundancy in this area. States have their own regulatory strategies to address government corruption, although independent assessments do not judge them to be particularly successful. 153 The federal government seems to share that view. The Justice Department created a Public Integrity Section within the Criminal Division in 1976, 154 and in the four decades since, federal prosecutors have [*893] aggressively prosecuted conduct of state and local officials that it determines breaches federal anti-corruption statutes. 155 For the past two decades, federal anti-corruption prosecutions of state and local officials typically average 350-400 per year. 156 Combatting "public corruption" is a top priority for the Federal Bureau of Investigation, on par with combating threats of terrorism, foreign espionage, and cyber-warfare. 157 And many of these prosecutions targeted wrongdoing far removed from property theft or quid pro quo bribery. 158 They extend to conduct involving undue influence, breaches of fiduciary duty, or failure to provide citizens with "honest services" 159 - wrongdoing for which the public harm is sometimes hard to identify. 160 [*894] By some accounts, including the U.S. Supreme Court's on occasion, 161 this enforcement agenda has been overly aggressive. 162 But Congress has generally encouraged far-reaching federal enforcement, notably by expanding the scope of federal anti-corruption law in response to narrow judicial interpretation. 163 And the key point here is that the federal executive Crime Victims are Criticized, Irish Times (Nov. 16, 2015), http://www.irishtimes.com/news/crime-and-law/new-laws-on-rights-of -crimevictims-are-criticised-1.2431095. By contrast, seeSinger v. United States, 380 U.S. 24, 34-37 (1965) (holding that due to judicial "confidence in the integrity of the federal prosecutor," U.S. attorneys need not give reasons for refusing to consent to defendant's waiver of jury trial).

Rev. 844, *894 Page 26 of 42 branch is firmly committed to a robust enforcement policy against local government corruption that is also criminalized under state law, and Congress has supported this agenda by enacting federal crimes intended to duplicate, or greatly overlap, state offenses. 164 In fact, federal statutes used in anti-corruption cases - [*895] like other federal criminal statutes - rely on and incorporate state law in federal offense definitions. In light of this structure, federal prosecutions can claim to effectuate state law goals - an especially straightforward version of federalism-based enforcement redundancy. 165 2. Sexual Assault In sharp contrast to public corruption, enforcement redundancy through coextensive jurisdiction is largely nonexistent for a large portion of the serious crimes that dominate state felony dockets, including sexual assaults, domestic violence, and homicide. 166 Federal law reaches only a small number of these offenses when they intersect a special basis for federal jurisdiction, such as interstate conduct - like human trafficking - or wrongs that occur on federal property or involve federal employees. 167 For most kinds of homicides, the lack of redundancy is only a modest hindrance to adequate enforcement; holding aside distinctive exceptions - such as homicides by police or racially motivated lynchings - there is little evidence to suggest patterns of homicide underenforcement in state justice systems. 168 Domestic violence and sexual assaults are a different story. Like local public corruption, sexual assaults have long been a key example of [*896] serious wrongdoing to which the responses of state and local criminal justice agencies have been deeply problematic. 169 Underenforcement is hard to measure for sexual assaults as it is in other contexts, but central features of the problem are clear enough. Rape and other forms of sexual assault are dramatically underreported crimes. 170 The leading government effort to collect data on sexual assaults (and other crimes), the National Crime Victimization Survey, is widely thought to undercount incidents of those offenses. 171 And rates of victim reports to police departments are even lower. The FBI Uniform Crime Reports collects data on sexual assaults reported to local police agencies; the number is consistently well below the annual number reported in the National Crime Victimization Survey. 172 One reason that victims do not to report rapes to law enforcement is the perception that police and prosecutors (as well as juries) are unduly skeptical of rape allegations. 173 And there is good evidence that law enforcement agencies' responses to 119 See In re Petersen, No. 2:10-CV-298 RM, 2010 WL 5108692, at 2 (N.D. Ind. Dec. 8, 2010) (concluding that prosecutors control charging decisions and certain victim rights under 18 U.S.C. § 3771(a), including the right ""to confer with the attorney for the Government in the case,' … arise only after charges have been brought against a defendant and a case has been opened," although a "victim's "right to be treated with fairness and with respect for [his or her] dignity and privacy,' … may apply before any prosecution is underway" (quoting 18 U.S.C. § 3771(a))); cf. United States v. Rubin, 558 F. Supp. 2d 411, 419 (E.D.N.Y. 2008) (assuming without deciding that some federal victim rights may apply before any prosecution is under way, but "cannot be read to include the victims of uncharged crimes that the government has not even contemplated … [or] has not verified to at least an elementary degree"). 120 Many state laws grant victims a right to consult only "after the crime against the victim has been charged" or "regarding the charges filed." Others create only a general right to confer, or "to communicate," "with the prosecution." E.g., Alaska Const. art. I, § 24 (granting "the right to confer with the prosecution"); Ariz. Const. art. 2, § 2.1(A)(6) (granting the right to "confer with the prosecution, after the crime against the victim has been charged, before trial or before any disposition of the case and to be informed of the disposition"); Cal. Const. art. I, § 28(b)(6) (granting the right to "reasonably confer with the prosecuting agency, upon request, regarding … the charges filed … ."); Idaho Const. art. I, § 22(5) (granting the right to "communicate with the prosecution"); Ill. Const. art. I, § 8.1(a)(4) (granting the right to "communicate with the prosecution"); Ind. Const. art. I, § 13(b) (amended 1996) (granting the right to "confer with the prosecution"); La. Const. art. I, § 25 (granting the "right to confer with the prosecution prior to final disposition of the case"); Mich. Const. art. I, § 24(1) (granting the "right to confer with the prosecution"); N.M.

Const. art. I, § 42(1)(f) (granting the "right to be consulted, upon request, regarding plea negotiations involving any violent felony"); S.C. Const. art. I, § 24(A)(7) (granting the right to "confer with the prosecution, after the crime against the victim has been charged, before the trial or before any disposition and informed of the disposition"); Tenn.

Code Ann. tit. 11, § 9405 (2018); Ga. Code Ann. § 17-17-11 (2018); Haw. Rev. Stat. § 801D-4(a)(1) (2017) (granting the right of victim to be informed of the final disposition of the case); Neb. Rev. Stat. 29-120 (2017) (requiring the prosecution to make a good faith effort to consult with victim); N.Y. Exec. Law § 642(1) (LexisNexis 2018) (providing standards for fair treatment of victims); Ohio Rev. Code Ann. § 2930.06(A) (LexisNexis 2018) (stating DAVID SCHOEN 103 Minn. L. Rev. 844, *896 Page 27 of 42 sexual assault reports are ineffective. Police clearance-by-arrest rates are low. 174 Detailed studies of how police departments handle reported sexual assault cases find "substantial attrition," [*897] typically at the point when police decide whether to make an arrest. 175 In the Los Angeles Police Department, only one report in nine was cleared by arrest; one in ten resulted in prosecution. 176 One hurdle lies in forensic evidence development: law enforcement agencies nationwide have suffered long backlogs in testing rape evidence kits, 177 although federal funding has recently helped reduce that problem. 178 Notoriously, things used to be much worse. Under the common law definition, rape convictions required proof that the offender used force to overcome the victim's "utmost resistance." 179 Evidence of women's - and only women's - prior sexual conduct or reputation for "unchastity" was a permissible basis on which to infer consent. 180 The law excluded rape of one's spouse from [*898] the offense definition. 181 Prosecutors and police were openly skeptical of rape accusations and reluctant to investigate. 182 Yet much of this legal infrastructure intended to restrict rape law enforcement has been abolished. Rape offenses have been revised to eliminate resistance requirements, and many states also removed the requirement to prove use of force. 183 Evidence rules are now more favorable to sexual assault complainants: rape shield laws in all jurisdictions prohibit use of a complainant's past sexual behavior as character evidence or a basis on which to infer consent, 184 while evidence rules in federal courts and nineteen states permit evidence of the defendant's past sexual offenses to show propensity to commit sexual assaults. 185 Some police departments have officers specially trained in sexual assault investigations, and prosecutors' offices (as required by statute in some states) have specially trained units dedicated to sexual assault prosecutions. 186 Hospitals and [*899] social service agencies likewise now have staff trained in forensic interviewing and evidence-gathering in the course of aiding assault victims. 187 that the "prosecutor … shall confer with the victim in the case before pretrial diversion is granted … [or] before amending or dismissing a charge"). 121 No rights of administrative review are specified in the state victims' rights laws cited supra note 120. 122 Five states place all their prosecutors within a single state agency, which at least potentially makes possible hierarchical oversight. In New Jersey, Connecticut, Rhode Island, Delaware, and Alaska, local prosecutors are appointed by, and under the supervision of, the state attorney general. See Steven W. Perry, Bureau of Justice Statistics, U.S. Dep't of Justice, Prosecutors in State Courts, 2005, at 2 (2006), https://www.bjs.gov/content/pub/pdf/psc05.pdf (noting Alaska, Connecticut, and New Jersey do not elect prosecutors; Delaware and Rhode Island elect attorneys general who appoint all prosecutors; all other states elect prosecutors at the local level). Id. at 11. For an example of a state attorney general's limited authority over locally elected prosecutors, see, for example,Va. Code § 2.2-511 (2018). 123 Equal protection and due process doctrines nominally empower courts to review charging decisions motivated by racial bias or retaliation for exercising fundamental rights, and inquiry into selective charging implicitly requires examining biased declinations as well. But these doctrines are wholly deferential to prosecutorial discretion. See United States v. Armstrong, 517 U.S. 456, 469 (1996) (holding that equal protection doctrine bars racially biased charging); Wayte v. United States, 470 U.S. 598, 607-08 (1985) (holding that due process bars charging in retaliation for exercising fundamental rights); see also McCleskey v. Kemp, 481 U.S. 279, 312-314 (1987) (holding that statistical evidence of bias in death penalty administration insufficient to prove constitutional violation without proving purposeful discrimination in defendant's case). For a classic account, see Kenneth Culp Davis, Discretionary Justice: A Preliminary Inquiry 188, 207-08 (1969) ("The affirmative power to prosecute is enormous, but the negative power to withhold prosecution may be even greater, because it is less protected against abuse… . The plain fact is that nine-tenths of local prosecutors' decisions are supervised or reviewed by no one."). DAVID SCHOEN 103 Minn. L. Rev. 844, *899 Page 28 of 42 This basic overview - drawn from a substantial scholarly literature - paints a somewhat contradictory picture. On the one hand, the primary story is one of longstanding underenforcement - a combination of explicit legal policies, practical evidencegathering and proof challenges, and cultural biases resulted in a notoriously weak response to sexual assaults by state criminal justice systems. On the other hand, there is a story, over the last forty years or so, of wide-ranging success in achieving reforms on several fronts - substantive and procedural law, institutional design, and resource allocation - designed to improve enforcement capacity. In other words, U.S. jurisdictions made substantial progress against an ingrained tradition of underenforcement without turning to any model of enforcement redundancy - federalization, private prosecution, or judicial review. That is more than state justice systems were ever able to do with regard to local government corruption, where the remedy instead was the rise of federal criminal law enforcement. And yet, few seem to consider this reform story a success. 188 The data on underreporting by victims, low arrest rates by police, and charging rates by prosecutors (along with the rape kit [*900] testing backlog) make it easy to view state criminal justice systems as failing to achieve adequate enforcement responses to sexual assaults despite the scope and gravity of the problem - 124,000 offenses reported to police in 2015, and 431,000 assault reports estimated by the National Crime Victim Survey. 189 This story of reform, its decidedly limited success, and the responses to that record all reveal insights about the prospects for redressing underenforcement through redundancy in this context. Intersecting feminist, victim rights, and rape-law-reform movements have achieved some remarkable reforms through the political process over the last four decades. U.S. criminal justice, like U.S. public law generally, is responsive to popular sentiment, well-organized reform movements, and interest groups. 190 But these movements never sought any mechanism of enforcement redundancy, and federal and state lawmakers never seriously considered one. Even now, when offense definitions, victim rights, evidentiary rules, and organizational changes in law enforcement agencies offer few plausible options for further improvement, there is effectively no sign of interest in private prosecution and judicial or administrative oversight. Instead, the sole focus of further innovation to address endemic underenforcement of sexual assault offenses is the federal government. And most federal policy - and policy proposals - stop short of expanding federal law to cover sexual assaults now within the jurisdiction solely of state courts. 191 A notable 124 Linda R.S. v. Richard D., 410 U.S. 614, 619 (1973) (rejecting private plaintiff's challenge on federal equal protection grounds to state policy of prosecuting only married men for failures to pay child support, concluding "in American jurisprudence at least, a private citizen lacks a judicially cognizable interest in the prosecution or nonprosecution of another"); Leeke v. Timmerman, 454 U.S. 83, 84 (1981) (extending Linda R.S. to hold that private citizens have "no cognizable interest" in process by which magistrates decide whether to issue warrants on criminal complaints); cf. Inmates of Attica Corr. Facility v. Rockefeller, 477 F.2d 375, 382-83 (2d Cir. 1973) (rejecting purported crime victims' request that court order prosecutors to charge). 125 See, e.g., Colo. Rev. Stat. § 16-5-209 (2017) ("The judge of a court having jurisdiction of the alleged offense, upon affidavit filed with the judge alleging the commission of a crime and the unjustified refusal of the prosecuting attorney to prosecute any person for the crime, may require the prosecuting attorney to appear before the judge and explain the refusal.

Olsen v. Koppy, 593 N.W.2d 762, 765-67 (N.D. 1999) (citing Lauder, 90 N.W. 564, with approval). 126 See Cal. Penal Code § 1385 (West 2016) ("The judge or magistrate may, either of his or her own motion or upon the application of the prosecuting attorney, and in the furtherance of justice, order an action to be dismissed."); Darryl K. Brown, Free Market Criminal Justice 35- 37 (2016); Valena E. Beety, Judicial Dismissals in the Interest of Justice, 80 Mo. L. Rev. 629, 640-43 (2015) (advocating for a shift in courtreviewed dismissals). DAVID SCHOEN 103 Minn. L. Rev. 844, *900 Page 29 of 42 exception is Professor Donald Dripps's current proposal to expand federal criminal law to cover most sexual assault offenses - precisely the model of federal-state enforcement redundancy that [*901] exists now for drug crimes, corruption, police violence, and much else. 192 But otherwise, existing policies and reform proposals emphasize more modest, although meaningful, federal efforts to improve state justice administration through, for example, funding grants (as for rape kit testing) 193 and occasionally by litigation to force institutional reforms in local agencies. In fact, federal law empowers the U.S. Justice Department to sue local police departments and other agencies, and authorizes structural injunctions to remedy systemic misconduct. 194 But the Department's use of this authority has largely focused on police violence rather than sexual assault underenforcement. 195 Various local law enforcement agencies have entered consent decrees under which they adopt institutional and policy reforms to reduce patterns of misconduct, even though federal intervention is hampered by the paucity of data on police misconduct, limited federal resources, and at times the political commitment of the presidential administration. 196 More to the point here, in only a few cases have federal officials targeted local agencies' inadequate responses to sexual assault. 197 In sum, and in sharp contrast to public corruption, the problem of underenforcement in the sexual assault context reveals the resistance, and cost, of U.S. criminal justice to institutional structures of enforcement redundancy. Having ruled out judicial review and private prosecution from the imaginations of reform-movement activists, the only alternative is the one that U.S. criminal justice always favors - federalism. Where federal criminal law takes on an enforcement agenda, it is usually effective. 198 Where tradition, politics, jurisdictional limits, or policy [*902] choices restrict the reach of federal law, as with sexual assault, the U.S. justice system is largely out of options. States were willing to change substantive and procedural law in hopes of improving rape prosecutions, but not to infringe prosecutors' monopoly control of charging by expanding modes of judicial, administrative, or private-party oversight. 3. Police Violence 127 New York granted courts nolle prosequi authority in 1829, during its era of private and judicially appointed prosecutors. McConville & Mirsky, supra note 81, at 35 (citing 1829 N.Y. Rev. Stat. tit. IV, § 68, p.730 & § 54. p.726). For a broad overview of state nolle pros laws, see Annotation, Power of Court to Enter Nolle Prosequi or Dismiss Prosecution, 69 A.L.R. 240 (1930). The federal rule is Fed. R. Crim. P. 48(a). Note that these rules give judges implicit power to compel prosecutors to litigate charges they would rather dismiss. For decisions insisting on judicial deference, see, for example, Genesee Prosecutor v. Genesee Circuit Judge, 215 N.W.2d 145, 147-48 (Mich. 1974). For similar examples in federal cases, see United States v. Smith, 55 F.3d 157, 159-60 (4th Cir. 1995); United States v. Perate, 719 F.2d 706, 710-11 (4th Cir. 1983); United States v. Smith, 853 F. Supp. 179, 183-84 (M.D.N.C. 1994); Dawsey v. Gov't of Virgin Islands, 931 F. Supp. 397, 402-04 (D.V.I. 1996). A standard explanation for deference is that judges lack means to compel prosecutors to litigate charges at trial. See, e.g., United States v. Greater Blouse, Skirt & Neckwear Contractors Ass'n, 228 F. Supp. 483, 489-90 (S.D.N.Y. 1964) ("Even were leave of Court to the dismissal of the indictment denied, the Attorney General would still have the right to … , in the exercise of his discretion, decline to move the case for trial. The Court in that circumstance would be without power to issue a mandamus or other order to compel prosecution of the indictment, since such a direction would invade the traditional separation of powers doctrine."). But judges have options short of mandamus. Presumably they could hold prosecutors in contempt for failures to appear, as they could for all other attorneys. And whenever prosecutors retain an interest charges they seek to dismiss, judges could incentivize them by ruling that failure to litigate charges results (as for civil parties) in forfeiture of the claim, or dismissal with prejudice. 128 For an overview of Canadian law on this point, see Mark Phillips, The Public Interest Criterion in Prosecutorial Discretion: A Lingering Source of Flexibility in the Canadian Criminal Process?, 36 Windsor Rev. Legal & Soc. Issues 43 (2015) (describing case law requiring great judicial deference to prosecutorial discretion). For Australia cases on prosecutorial discretion, see Miller v Commonwealth Dir. of Pub. Prosecutions [2005] 142 FCR 394, 399-400 (Austl.). 129 Manikis, supra note 60, at 29. In addition, many nineteenth-century state courts justified privately funded prosecutions by citing the public value of these contributions to supplement underfunded district attorney offices. See Ireland, supra note 83, at 47, 49-51 (citing and quoting multiple state courts). Private prosecutors may have different reasons to proceed when despite comparatively low odds of winning a conviction. Some of those motivations, at least, can be public-regarding. Avlana Eisenberg makes the point that prosecuting hate crimes cases, for example, can have expressive and educative value that justifies pursuing well-grounded cases despite skeptical juries. Eisenberg, supra note 45, at 893-95, 902-18. 130 For discussions on the common law aversion to private prosecution, see Ireland, supra note 83 and for a review of the impact of racial tensions on private prosecution, see Blackmon, supra note 98. DAVID SCHOEN 103 Minn. L. Rev. 844, *902 Page 30 of 42 Responses to unjustified police violence reveal a third outcome for enforcement redundancy confined to the federalism model. Federal enforcement authority extends to cases of police violence to a much greater degree than for sexual assaults. That authority extends as well to other kinds of bias-motivated wrongdoing by both private actors and government officials, which local police and prosecutors have at times ignored or devalued, and for which state-level enforcement commitment continues to be uneven. 199 Federal jurisdiction is coextensive with state jurisdiction regarding police wrongdoing, and the Justice Department's institutional capacity for enforcement probably exceeds that of its state counterparts, but in one respect the overlap is not complete. The key substantive criminal offenses available to prosecutors in the federal code are somewhat more restrictive. The primary federal statute used to charge cases of [*903] police excessive use of force requires proof of willful deprivation of rights, 200 a strict mens rea standard that makes it harder for federal prosecutors to prove liability than it would be for state prosecutors relying on typical assault or homicide offense definitions. 201 The fact that Congress has for decades let stand this mens rea hurdle to excessive-force prosecutions suggests that federal legislators, if not Justice Department officials, are less committed to a full federal-state enforcement redundancy - or "to altering the federal-state balance in order to reinforce state law enforcement" - than they are for public corruption offenses. 202 That limit notwithstanding, federal prosecutions in this area have a track record of succeeding where state prosecutions failed or were never attempted, and in that way providing at least a partial remedy for underenforcement by state criminal justice officials. Much of the federal advantage comes from the fact that federal prosecutors are, in general, better situated to objectively investigate, assess, and prosecute wrongdoing by police officers than are local prosecutors who ordinarily interact with and depend upon those officers (or at least their agencies). This is not a particular criticism of local prosecutors' offices; it is one instance of the basic problem that officials (and people generally) are untrustworthy judges of the conduct of others with whom they have affiliations, allegiances, or ongoing relationships. For that reason a few states assign such cases to state-level, rather than local, officials. 203 And the U.S. Justice Department attempts to collect data on deaths in jails, prison, or during [*904] attempted arrests, to facilitate Justice Department oversight. 204 The same concerns motivate English laws applying special judicial scrutiny (when triggered by requests from victims' families) to prosecutor's decisions not to charge in the case of death caused by law enforcement officials or occurring in official custody. 205 131 Some federal states such as Germany and Canada lack enforcement redundancy because they use a single, nationwide, criminal code, which is enforced for prosecution agencies and courts organized at the state or provincial level. See generally Eric P. Polten & Eric Glezl, Federalism in Canada and Germany: Overview and Comparison (2014) (describing similarities in German and Canadian federalism, including allocating authority over substantive criminal law to the federal government but criminal justice administration to state or provincial prosecutors and courts). In Australia, like in the United States, states and the federal government each have their own criminal codes. But Australian federal criminal authority is confined much more narrowly than in the United States to conduct that implicates a distinct federal interest. See generally Arther B. Gunlicks, The Lander and German Federalism 59, 72, 129 (2003) (describing German criminal affairs and jurisdictions as compared to the United States); Polten & Glezl, supra, at 5-6, 10, 13-14; Brian Galligan, Comparative Federalism, in The Oxford Handbook of Political Institutions 261, 266-75 (Sarah A. Binder et al. eds., 2008) (discussing federalism and judicial review and regulations); Kathleen Daly & Rick Sarre, Criminal Justice System: Aims and Processes, in Crime and Justice: A Guide to Criminology 357 (Darren Palmer et al. eds., 5th ed. 2017) (examining the processes and purposes of the criminal justice system); Vicki Waye & Paul Marcus, Australia and the United States: Two Common Criminal Justice Systems Uncommonly at Odds, Part 2, 18 Tul. J. Int'l & Comp. L. 335 (2010) (highlighting similarities and differences between the two countries in relation to criminal laws and policies). 132 Since 2011, Switzerland also now has unified national criminal law and procedure codes administered in all cantons. See Anna Petrig, The Expansion of Swiss Criminal Jurisdiction in Light of International Law, 9 Utrecht L. Rev. 34, 36 (2013). 133 See Director of Public Prosecutions Act 1983 s 10(2); Annual Report 2014-15, supra note 71. 134 In unusual circumstances, two states may also have concurrent jurisdiction over the same crime, enabling one to assess the adequacy of the other's enforcement effort. For a rare example, see Heath v. Alabama, 474 U.S. 82, 91-93 (1985). 135 See U.S. Const. amend. V (Double Jeopardy Clause); Bartkus v. Illinois, 359 U.S. 121, 136-39 (1959) (affirming power of state to prosecute defendant after a federal prosecution for the same bank robbery); United States v. Lanza, 260 U.S. 377, 384-85 (1922) (approving federal prosecution after state prosecution based on same conduct). DAVID SCHOEN 103 Minn. L. Rev. 844, *904 Page 31 of 42 U.S. victims lack a right to challenge noncharging decisions in cases of homicides by police. But they, along with organized interest groups, can lobby prosecutors to prosecute. In some cities, voters and activist groups have pressured local prosecutors on police violence cases. 206 It is difficult to assess what role public sentiment plays (and should play) in charging decisions. But it is not hard to find instances of potent political challenges to non-prosecution of police officers in the wake of fatal shootings. Chief prosecutors in Cleveland, Ohio, and Chicago, Illinois, lost reelection bids in the wake controversial failures to charge police officers in fatal-shooting cases. 207 In the midst of popular and activist attention on such cases, prosecutors in several other cities have charged officers for offenses related to suspects' deaths, with mixed records of success. 208 Chicago prosecutors did so a year [*905] after police fatally shot a suspect and only upon public release of video of the incident 209 - a scenario that suggests public attention corrected a noncharging decision influenced by improper considerations. However, U.S. localities vary widely in their demographics, politics, and community sentiments toward these cases. 210 That variation, plus local election of prosecutors, contributes to widely varying enforcement policies across prosecution offices. 211 And it means victims who urge prosecutions when local majority sentiment disfavors it have lower odds of successfully influencing [*906] prosecutors. The political variability of local prosecutors' charging policies - and the vulnerability of those decisions to local sentiment that favors unjustified underenforcement - are a key reason federal redundancy is important in this context. Given that police misconduct is an established part of the U.S. Justice Department's enforcement agenda, federal prosecutors should be a check on political judgments of local prosecutors. They also provide victims with a different agency to appeal to for investigation and prosecution. This federalism-based model of redundant enforcement has advantages as a strategy to reduce risks of unmerited underenforcement. The alternative model authorizing judicial review of declination decisions, as is used in England, relies on the independence of judges from the prosecutors whom they review. 212 The federalism model relies on the independence of federal prosecutors from state prosecutors and police. The executive branch of one sovereign scrutinizes the enforcement response of another. And it has the capacity to act on its independent judgment, while courts are confined to ordering 136 See United States v. Gamble, 694 Fed. App'x. 750 (11th Cir. 2017), cert. granted, Gamble v. United States, 138 S. Ct. 2707 (2018). Even if the Court abolishes the dual sovereignty doctrine in Gamble, federal and state prosecutors will continue to be able to prosecute the same offenders for the same conduct in many cases. Under Blockburger v. United States, 284 U.S. 299, 304 (1932), the Double Jeopardy Clause precludes multiple prosecutions only if the subsequent charge has the "same elements" as the first. See United States v. Dixon, 509 U.S. 688, 696 (1993) (affirming Blockburger's same-elements test as the sole basis for double jeopardy claims). Unlike the firearm offenses that gave rise to Gamble's Double Jeopardy claim, federal and state crimes covering the same conduct often have distinct elements. For an example, see infra notes 200-02 and accompanying text. 137 See, e.g., U.S. Dep't of Justice, United States Attorneys' Manual, supra note 55, § 9-2.031 (explaining the "Petite policy" criteria for federal prosecution of same conduct after state prosecution). 138 For an example of a high-profile federal declination in the wake of state declination, see U.S. Dep't of Justice, Department of Justice Report Regarding the Criminal Investigation Into the Shooting Death of Michael Brown by Ferguson, Missouri Police Officer Darren Wilson 5-9 (2015), https://www.justice.gov/sites/default/files/opa/pressreleases/attachments/2015/03/04/doj_report_on_shooting_of_michael_brown_1.pdf.

By contrast, prosecutors rejected only about 23 percent of referrals in all other types of criminal cases"). 139 See, e.g., Koon v.

Rev. 844, *906 Page 32 of 42 prosecutors to reverse their earlier non-prosecution decisions (or, occasionally, to appointing substitute prosecutors). This "executive separation of powers" model has proven effective, although whether it is effective enough is debated; it depends on whether all cases of police violence that should have been prosecuted - based on the evidence and the public interest in enforcement - were prosecuted. State and federal prosecution offices have distinct professional cultures and are responsive to different constituencies and modes of political supervision, which increases the independence of one from the other. 213 On the other hand, federal prosecution is still to some degree political; it varies with the policy priorities of presidential administrations 214 to a degree that judicial review [*907] (in theory) should not. When there is less federal commitment to oversight of states' approaches to police violence, enforcement redundancy is weak. 215 Victims and other interested parties have no other recourse. C. Underenforcement and Prosecutor Political Accountability In short, U.S. strategies of enforcement redundancy have a relatively strong track record for some crimes such as public corruption, are robust but vulnerable to political shifts for others such as a police violence, and are notably weak with regard to certain offenses, such as sexual assaults. That last category is important because that weakness extends well beyond sexual assault offenses; many of the routine crimes that make up typical state criminal dockets are not within the scope of federal criminal law enforcement. And since private prosecution and judicial or administrative review of prosecutorial decisions are almost completely absent from state criminal justice systems, there is no charging-decision oversight of state prosecutors' declination decisions and enforcement policies - save for local electoral accountability. In forty-five of fifty states, chief prosecutors are directly elected in local constituencies. 216 This form of democratic accountability operates as a kind of check on underenforcement, although it has significant limits in its capacity to play that role. State prosecutors' elected status is likely the best explanation [*908] for why victim-based checks on declination - private prosecution or judicial review - never became a part of victims' rights reforms enacted in U.S. jurisdictions in recent decades. First, prosecutors are politically powerful groups with legislatures, and they zealously guard their unfettered discretion over criminal charging. 217 Second, it has led even courts to disfavor any degree of judicial review of charging decisions, on the On Justice Department professionalism, see Jim McGee & Brian Duffy, Main Justice: The Men and Women Who Enforce the Nation's Criminal Laws and Guard Its Liberties 7-9 (1996); Jed Handelsman Shugerman, The Creation of the Department of Justice: Professionalization Without Civil Rights or Civil Service,66 Stan. L. Rev. 121, 125-26 (2014). 142 The arguable exceptions are federal crimes for race-based and civil rights-related violence and for local officials' abuses of power; in those realms federal authorities responded to widespread failures by state law enforcement and justice systems. See generally Michal R. Belknap, Federal Law and Southern Order: Racial Violence and Constitutional Conflict in the Post-Brown South 154-58 (1987) (highlighting the federal response to southern violence in mid-twentieth century); Rhodri Jeffreys-Jones, The FBI: A History 19-24 (2007) (tracing FBI to nineteenth century federal efforts to combat Ku Klux Klan terrorism of voters); William J. Stuntz, The Collapse of American Criminal Justice 99-157 (2011) (documenting the expansion of federal role in law enforcement and prosecution in the late nineteenth century). 143 See infra Part III.B.1. 144 See, e.g., Screws v. United States, 325 U.S. 91, 110-14 (1945). 145 For an indication that federal enforcement policy is designed to protect specific victim interests, see U.S. Dep't of Justice, FY 2014 Annual Performance Report and FY 2016 Annual Performance Plan I-16-17 (2015), https://www.justice.gov/sites/default/files/doj/pages/attachments/2015/02/06/fy2014aprfy_2016app2.pdf (describing aspects of the "Vulnerable People Priority Goal"). 146 See Lichtblau, supra note 141. 147 See Paul G.

Rev. 844, *908 Page 33 of 42 rationale that oversight of prosecutors lies in the political process rather than judicial enforcement of legal parameters for charging. 218 Third, popular and political pressure has succeeded in redressing some underenforcement practices by prosecutors (and police) when victim groups, or issues tied to specific offenses, achieve political potency. Intoxicated driving is perhaps the best example of harmful wrongdoing about which many enforcement agencies have successfully revised their policies to increase enforcement. 219 Domestic violence and sexual assaults are other examples where enforcement shifts have been more limited but still significant. 220 Responses by local agencies to this type of pressure have taken three basic forms. First, chief prosecutors adopted internal office policies that mandate - or set a strong presumption for - [*909] prosecution of specific crimes when evidence is sufficient. 221 Second, prosecutors get specialized training on how to address the particular challenges posed by specific kinds of cases such as domestic violence or sexual assault. 222 Finally, many offices have established dedicated, in-house units of prosecutors who specialize in these same kinds of crimes. 223 States legislatures have encouraged these reforms, 224 but virtually everywhere, the adoption, content, and enforcement of policies is left to local chief prosecutors. No legislation sets specific charging criteria, authorized judicial review, or gives enforceable rights to victims. 225 These responses to underenforcement are meaningful, but their form is more political than legal. They are the kinds of responses produced by a system of electorally accountable prosecutors and legislatures. 226 Often they are in large part attributable to successful political efforts by advocacy groups. Mothers Against Drunk Driving (MADD), for example, successfully urged reforms of laws and enforcement practices against intoxicated driving. 227 Feminist groups and women's advocates play important, ongoing roles in reforming police and prosecution policies, substantive criminal laws, and evidence rules for domestic [*910] violence and sexual assault offenses. 228 These efforts have succeeded in changing attitudes, professional cultures, and enforcement practices in police and prosecution agencies that had contributed to underenforcement in these areas. 229 Prosecution units specializing in offenses such as domestic violence, for example, strengthen professional culture committed to enforcement by attracting lawyers who share that commitment and who develop expertise to act on it. 230 https://papers.ssrn.com/sol3 /papers.cfm?abstract_id= 3095741. Without grounds for federal jurisdiction - such as conduct involving interstate travel or occurring on federal property - sexual assaults and other violent offenses are the exclusive province of state officials.

Rev. 844, *910 Page 34 of 42 Successes notwithstanding, reliance on this kind of political supervision cannot be an equally effective remedy for underenforcement across all contexts. The independence of local prosecution and police agencies means that policies, resources, and constituent support for rigorous enforcement inevitably vary. 231 They will differ not only across localities but also according to the type of offense and the identity of the victim. Some groups, such as victims of intoxicated drivers, can succeed at achieving more rigorous enforcement policies. 232 Other victims with less political support or popular sympathy - undocumented immigrants, sex workers, prison inmates, and casualties of police shootings 233 - have dimmer prospects when prosecutors are responsive to local majorities' preferences. In some places, public [*911] sentiment is a force in favor of charging in categories of wrongdoing that have suffered from patterns of underenforcement. In other places, the same can be a force against charging and can reinforce underenforcement practices. Either way, electoral accountability can lead to undue pressure on prosecutors to yield to majoritarian or interest-group pressure to avoid "commiting political suicide." 234 In short, political supervision, as an institutional structure to minimize unjustified failures to prosecute, is an institutional structure with a highly uneven track record and decidedly mixed prospects. On the other hand, some of the strategies for enforcement redundancy examined above that take the form of legal entitlements would likely also achieve partial success. Private prosecution is an unpromising device to aid certain marginalized victim groups such as inmates, undocumented immigrants, or low-income people generally. Other options - review of declination by courts, or concurrent jurisdiction of a separate prosecution agency - hold somewhat more promise. Judicial review is somewhat more removed from political influence (though perhaps less so in jurisdictions that elect judges), 235 although that mechanism still depends on victims to petition for review. The overlap of federal and state criminal jurisdiction subjects enforcement to review by a rival agency subject to, at worst, different political influences. At best, as with a Justice Department that can minimize political influence with professional and bureaucratic norms, it expands the prospect for less political review. 236 (criticizing the use of federal convictions data in public corruption analysis and advocating instead for the use of administrative data).

DAVID SCHOEN 103 Minn. L. Rev. 844, *911 Page 35 of 42 [*912] CONCLUSION All justice systems suffer from pockets of unjustified, even pernicious, underenforcement. All recognize that public prosecutors can be vulnerable to biases and institutional interests that distort enforcement decisions. Especially in recent decades, nearly all have adopted mechanisms to address those risks. Outside the United States, victim rights legislation has included provisions directed at unjustified decisions not to prosecute. In other common law countries and in Europe, most victims may now either seek independent review of prosecutors or initiate prosecutions on their own. Independent review keeps the safeguard against underenforcement in public hands while strengthening the principle that charging decisions should be nonpolitical and ministerial in nature. Victim rights reforms in general manifest a judgment that modern criminal justice had focused excessively on public interests and unduly neglected victims' private interests in criminal prosecutions. Authorizing victims to challenge declination decisions extends this idea by recognizing victims' private stake in those decisions and enabling victims to serve the public interest in preventing unjustified failures to prosecute. 237 Virtually all U.S. jurisdictions reject both of those strategies. 238 And rather than insulate their prosecutors from political [*913] influence, most states rely on electoral politics for oversight of prosecution practices. Instead, the U.S. model opts for duplicative federal-state jurisdiction against a background of politically attuned state prosecutors. Both this federalism model of redundant prosecutorial authority - which may be reduced this term by the Supreme Court's decision in Gamble - and the model of politically responsive prosecutors have proven effective at redressing some types of underenforcement. Both serve some victims' interests without taking the form of victim rights. And both reflect a preference for political over legal safeguards against biased or ill-conceived uses of prosecutorial discretion. American criminal justice is more sanguine than other legal systems about the downsides of prosecutors' electoral accountability and attention to majoritarian sentiments. U.S. prosecutors' democratic legitimacy works against arguments for more formal oversight or regulation. Even against the potent political power of victims' rights movements, unfettered executive charging discretion has proven immutable. 239 But federal prosecutors provide significant oversight, at least for some 160 United States v. Alfisi, 308 F.3d 144, 155-56 (2d Cir. 2002) (Sack, J., dissenting) (arguing that payments to federal officials prosecuted under 18 U.S.C. § 201 caused no clear harm or "corruption"); Mills & Weisberg, supra note 150, at 1373-74 (discussing the role of fiduciary duties in criminal liability); id. at 1377, 1386-90, 1404-05 (discussing uncertainty of "harm" in some contexts); id. at 1395-1400 (discussing honest services); Lex Hemphill, Acquittals End Bid Scandal that Dogged Winter Games, N.Y. Times, Dec. 6, 2003, at D1 (reporting a federal district judge's criticism of the prosecution, saying "in his 40 years of working in the criminal justice system, he had never seen a case so devoid of "criminal intent or evil purpose'"). 161 For Supreme Court decisions rejecting broad applications of federal anti-corruption statutes, see generally McDonnell v. United States, 136 S. Ct. 2355 (2016) (reversing the former Virginia Governor's conviction for honest-services fraud and extortion); McNally v. United States, 483 U.S. 350 (1987) (reversing the conviction of state officials and holding that federal mail fraud statute, 18 U.S.C. § 1341, does not apply to schemes to defraud state citizens of the intangible "right to have the Commonwealth's affairs conducted honestly"). As a matter of statutory interpretation, the Court requires a "clear statement" that Congress intends a federal criminal statute to duplicate a state crime and thereby "effect a significant change in the sensitive relation between federal and state criminal jurisdiction." United States v. Bass, 404 U.S. 336, 349-50 (1971); see also Rewis v. United States, 401 U.S. 808, 811-12 (1971). But Congress has made such intent sufficiently clear for the Court in numerous statutes, including those at issue in Bass (18 U.S.C. § 1202(a), now codified at 18 U.S.C. § 922(g)) and in Rewis (18 U.S.C. § 1952). See, e.g., Perrin v. United States, 444 U.S. 37, 50 (1979) (finding that § 1952 reflects congressional intent "to alter the federal-state balance in order to reinforce state law enforcement"). 162 See, e.g., Roderick M.

Similar strategies of offense reform and creation of dedicated prosecution units have more recently been strategies against another context of endemic underenforcement - crimes against inmates.

See id. at 59-61 (describing injunctive relief under 42 U.S.C. § 14141, noting limits on data about police misconduct, and explaining how insufficient data limits the effectiveness of reform efforts).
