Research summary Crime and violence continue to be problems that plague urban areas across the United States and the globe. One key approach for responding to these problems is “focused deterrence” which includes programs that prevent criminal behavior by blending criminal justice, social service, and community‐based action. While previous systematic reviews have supported the crime control effectiveness of focused deterrence, prior reviews have not included randomized experimental evaluations which are generally recognized to provide stronger causal claims when implemented with fidelity. This updated review of 50 controlled evaluations benefits from the addition of 26 rigorous studies, of which 9 are randomized experimental field trials. This suggests the importance of reassessing the evidence and provides opportunities for additional moderator analyses of program impacts. The overall meta‐analysis suggested that focused deterrence was associated with a statistically significant 23% crime reduction in treatment groups relative to control groups. Meta‐analysis of the 9 randomized experiments suggested focused deterrence generated a smaller 16% crime reduction. Programs designed to reduce gang and group‐involved gun violence were associated with the largest crime reduction impacts. Studies that examined community outcomes generally observed positive impacts. Policy implications A much more rigorous scientific evidence base now exists to support the continued use of focused deterrence to control crime and violence. These analyses, which include randomized controlled trials, provide robust and consistent evidence that focused deterrence reduces crime. Moreover, preliminary results from a group of studies that measure community outcomes, suggest that community residents have positive perceptions of these programs. Program implementation remains challenging with studies noting persistent problems with treatment integrity and sustainability. Further research is also needed to clarify prevention mechanisms so key program activities can be better understood and enhanced.
犯罪和暴力仍然是困扰美国乃至全球城市地区的问题。应对这些问题的一个关键方法是“集中威慑”,包括通过混合刑事司法、社会服务和社区行动来预防犯罪行为的计划。虽然以前的系统评价支持集中威慑的犯罪控制有效性,但以前的评价没有包括随机实验评估,这些评估通常被认为在忠实执行时提供更强的因果关系主张。这份对50项对照评价的最新综述得益于新增的26项严格研究,其中9项是随机实验现场试验。这表明重新评估证据的重要性,并为项目影响的额外调节分析提供了机会。总体荟萃分析表明,与对照组相比,治疗组的集中威慑与统计学上显著的23%的犯罪率降低相关。对9个随机实验的荟萃分析表明,集中威慑减少了16%的犯罪。旨在减少帮派和团体参与的枪支暴力的项目与减少犯罪的最大影响相关。调查社区结果的研究通常观察到积极的影响。政策影响现在有了更加严格的科学证据基础来支持继续使用集中威慑来控制犯罪和暴力。这些分析,包括随机对照试验,提供了强有力和一致的证据,证明集中威慑可以减少犯罪。此外,一组衡量社区成果的研究的初步结果表明,社区居民对这些项目有积极的看法。项目的实施仍然具有挑战性,研究表明治疗的完整性和可持续性存在持续问题。还需要进一步研究以阐明预防机制,以便更好地了解和加强关键的方案活动。

Research Summary

Second-chance hiring, or an employer's commitment to hiring (at least some) people with criminal records, is simultaneously an ongoing public movement and an opaque process. To examine perceptions of second-chance policies and employers, we analyzed interview data from formerly incarcerated adults in the Greater Boston area. We find that a small portion was familiar with Ban-the-Box (BTB), a policy that had been in effect locally for more than a decade; after learning about the policy, participants indicated that it was a promising start but could unintentionally provide false hope if employers conduct criminal background checks soon thereafter. We then asked for definitions of criminal record (or in our study context, “CORI”) friendly employers. Participant descriptions fell into three categories: exclusionary, CORI-friendly under certain circumstances, and fully inclusive. Descriptions of the sometimes-friendly employers reflected individualized assessments, where the criminal history and context seemed to matter. Although partial exclusion was not ideal to participants, even the most well-reputed inclusive jobs—those connected to labor unions—carried cautions from union-member participants. Finally, we explored whether submitting evidence of rehabilitation is feasible. Most participants indicated they could readily provide a recommendation letter and/or accomplishments to an employer if provided the opportunity—but few reported having this experience.

Policy implications

Examining the perceptions of job applicants with criminal records can provide insight into both problems and possibilities. Existing counterintuitive empirical findings on BTB may be driven, in part, by job applicants with criminal records not being aware of (and therefore not responding to) policy changes. Even after being informed, skepticism of BTB points to the importance of employer responses throughout the decision process. We recommend four policy pathways: increasing awareness of existing policies, expanding CORI-friendliness through employer engagement, promoting broader culture change, and incorporating positive credentials into individualized assessments through formalized processes.

第二次招聘,或雇主承诺雇用(至少一些)有犯罪记录的人,同时是一个正在进行的公共运动和一个不透明的过程。为了检验人们对第二次机会政策和雇主的看法,我们分析了来自大波士顿地区曾经被监禁的成年人的访谈数据。我们发现,一小部分人熟悉“禁盒”(BTB)政策,这一政策在当地已经实施了十多年;在了解了这项政策后,参与者表示,这是一个有希望的开始,但如果雇主很快就进行犯罪背景调查,可能会无意中给人带来虚假的希望。然后,我们要求对犯罪记录(或在我们的研究背景下,“CORI”)友好的雇主给出定义。参与者描述分为三类:排除性、在某些情况下对CORI友好、完全包容。对有时友好的雇主的描述反映了个性化的评估,其中犯罪历史和背景似乎很重要。虽然部分排除对参与者来说并不理想,但即使是那些与工会有关的最知名的包容性工作,也会受到工会成员参与者的警告。最后,我们探讨了提交康复证据是否可行。大多数参与者表示,如果有机会,他们很乐意向雇主提供推荐信和/或成就,但很少有人报告有这样的经历。政策含义检查有犯罪记录的求职者的看法可以洞察问题和可能性。现有的关于BTB的反直觉的实证研究结果,可能部分是由于有犯罪记录的求职者不知道(因此也没有对)政策变化做出反应。即使在被告知之后,对BTB的怀疑也指出了雇主在整个决策过程中的反应的重要性。我们推荐了四种政策途径:提高对现有政策的认识,通过雇主参与扩大CORI友好性,促进更广泛的文化变革,并通过正式流程将积极的证书纳入个性化评估。

Research Summary

Miller v. Alabama and Montgomery v. Louisiana restricted states’ ability to impose life without parole for youth under age 18 (henceforth JLWOP). Since Miller, 46 pieces of legislation across 34 states and the District of Columbia have altered JLWOP sentencing policies. The current study provides the first comprehensive and scientific review of this legislation. Using policy surveillance as a methodological guide, we found that a majority of statutes (N = 28) ban JLWOP sentencing, above and beyond the Supreme Court's requirement. Many statutes also extended sentencing reforms and post-conviction relief eligibility to other types of sentencing beyond JLWOP. However, all but one statute still allows either JLWOP or life with parole as a sentencing option for minors convicted of homicide crimes and requires between 15 and 40 years, at minimum, to be served before being eligible for release. Grounding our analysis in institutional theory, we argue that the relative punitivity of the JLWOP reforms enacted was associated with measures of JLWOP institutionalization across states (i.e., pre-Miller JLWOP population and pre-Miller sentencing schema), suggesting that states where JLWOP was more routinely used were more resistant to policy reform.

Policy Implications

The current study provides implications for future decarceration efforts. Findings suggest that state legislatures are willing to enact post-conviction relief measures (e.g., judicial review or “second look” measures) for individuals convicted of violent crimes to address over-incarceration, deviating from previous decarceration efforts focused on non-violent, low-level offenses. In spite of the promising window for juvenile justice reform that Miller provided, however, these reforms have taken a relatively modest, incremental approach toward altering extreme youth sentencing practices in the United States. Policy makers and advocates seeking to promote sentencing reform efforts should factor in how highly institutionalized a sentencing practice is in each state, as this might inform effective strategies for policy change.

米勒诉阿拉巴马州案和蒙哥马利诉路易斯安那州案限制了各州对18岁以下青少年(以下简称JLWOP)实施无假释终身监禁的能力。自米勒案以来,34个州和哥伦比亚特区的46项立法改变了JLWOP的量刑政策。目前的研究首次对这一立法进行了全面和科学的审查。使用政策监督作为方法指南,我们发现大多数法规(N = 28)禁止JLWOP判决,超出了最高法院的要求。许多法规还将量刑改革和定罪后救济资格扩展到JLWOP以外的其他类型的量刑。然而,除了一项法规外,其他所有法规仍然允许对犯有杀人罪的未成年人判处有期徒刑或假释终身监禁,并要求至少服刑15至40年才有资格获释。在制度理论的基础上,我们认为,实施的JLWOP改革的相对惩罚性与各州的JLWOP制度化措施(即米勒之前的JLWOP人口和米勒之前的量刑模式)有关,这表明JLWOP更经常使用的州对政策改革的抵抗力更强。当前的研究为未来的脱碳工作提供了启示。研究结果表明,州立法机构愿意为被判犯有暴力罪行的个人制定定罪后救济措施(例如,司法审查或“二次审视”措施),以解决过度监禁问题,而不是以往专注于非暴力、低级别犯罪的解除监禁努力。尽管米勒为青少年司法改革提供了一个有希望的窗口,然而,这些改革在改变美国极端青少年量刑实践方面采取了相对温和的渐进式方法。寻求促进量刑改革努力的政策制定者和倡导者应该考虑量刑实践在每个州的高度制度化程度,因为这可能为政策变化提供有效的策略。

Rethinking rules for 911: Dispatching alternative responders in Denver and San Francisco 重新思考911规则:在丹佛和旧金山派遣替代救援人员

Research Summary

Alternatives to police response to 911 calls have emerged as a leading public safety reform strategy. A key policy implementation challenge lies in determining whether alternative responders, police, or both are most appropriate for a given situation—a decision that largely falls to 911 call takers and dispatchers. This article examines how dispatch organizations have tried to structure these decisions through protocols and decision trees. Drawing on 39 interviews and 20 h of observations with 911 workers in San Francisco and Denver, we argue that these tools, as currently structured, are poorly suited to handle the uncertainty, subjectivity, and ambiguity that characterize many street crisis calls. In the absence of more thoughtfully designed guidance from leadership, we find that dispatch staff routinely work around the rules to attain the response they believe is most appropriate.

Policy Implications

Addressing the dispatch protocol issue is critical for the success of the alternative response movement. Absent workable protocols, dispatchers sometimes default to sending the police, undermining the progress alternative response promises. Applying our learnings from Denver and San Francisco, this study points to a two-pronged approach that dispatch agencies can use to improve call diversion guidance. First, they can refine existing protocols and decision trees by grounding them in the experiential knowledge of frontline staff. Second, they can supplement these tools with more flexible forms of guidance—such as organizational value statements or collaborative decision-making frameworks—to aid decision making when protocols reach their limits. Together, these changes can produce guidance that is more responsive to the realities of dispatch work and better aligned with the goals of alternative response.

替代警察对911电话的回应已经成为一项主要的公共安全改革战略。政策实施的一个关键挑战在于确定备选响应者、警察还是两者都最适合特定情况,这一决定主要落在911接线员和调度员身上。本文考察了调度组织如何尝试通过协议和决策树来构建这些决策。根据对旧金山和丹佛911工作人员的39次访谈和20小时的观察,我们认为这些工具,就目前的结构而言,不适合处理许多街头危机呼叫特征的不确定性、主观性和模糊性。我们发现,在缺乏领导层精心设计的指导下,派遣人员通常会绕过规则,以获得他们认为最合适的回应。解决调度协议问题对于备选响应运动的成功至关重要。由于缺乏可行的协议,调度员有时会默认派遣警察,从而破坏了其他响应承诺的进展。结合丹佛和旧金山的经验,本研究指出了调度机构可以采用双管齐下的方法来改进呼叫分流指导。首先,他们可以根据一线员工的经验知识来完善现有的协议和决策树。其次,他们可以用更灵活的指导形式(如组织价值声明或协作决策框架)来补充这些工具,以便在协议达到极限时帮助制定决策。总之,这些变化可以产生更符合派遣工作实际情况和更符合替代性反应目标的指导。

Drug decriminalization and policy alienation among frontline police in British Columbia: A qualitative study 不列颠哥伦比亚省一线警察毒品非刑事化与政策疏离:一项定性研究

Research Summary This qualitative study examines how frontline police officers in British Columbia experienced and adapted to Canada's first formal drug decriminalization policy 1 year after implementation. Drawing on 30 semi‐structured interviews and using thematic analysis with a policy alienation and street‐level bureaucracy lens, we analyzed how officers felt alienated from the policy process and coped with this experience as frontline implementers. Key themes show that frontline officers experienced processes of policy alienation in various ways: they felt that the policy was misaligned with their frontline perspectives; the Policy undermined their ability to help people in their communities; and legal ambiguity surrounding the Policy was challenging to navigate. Their coping strategies revealed that officers interpreted and executed decriminalization in divergent ways. Policy Implications These findings have important implications for policymakers and police leadership considering drug policy reforms. Officers’ feelings of disempowerment and policy meaninglessness, especially in contexts of legal ambiguity, may lead to inconsistent or inequitable enforcement. Strengthening communication across police ranks is critical. Middle managers may help translate reform goals, identify resource gaps, and support effective coping strategies. Legal clarity should extend beyond policy updates to help officers reconcile overlapping laws and reduce liability concerns. While there are limits to policy consultation with frontline officers within the hierarchical structure of police institutions, reform efforts should still engage with frontline officers’ working logics. Training should address harmful attitudes and misunderstandings of drug use, clarify legal boundaries, and mitigate unintended harms of enforcement. Ultimately, effective drug policy reform in a multi‐jurisdictional system requires acknowledging how frontline officers interpret and shape policy within institutional constraints.
这项定性研究考察了不列颠哥伦比亚省的一线警察在实施加拿大第一个正式的毒品非刑事化政策一年后是如何经历和适应的。利用30个半结构化访谈,并使用政策疏离和街头官僚主义视角的专题分析,我们分析了官员如何感到与政策过程疏离,以及作为一线实施者如何应对这种经历。主要主题显示,前线人员在不同方面经历了政策异化的过程:他们觉得政策与他们的前线观点不一致;该政策削弱了他们帮助社区内人民的能力;围绕该政策的法律模糊性也很难驾驭。他们的应对策略表明,警官们以不同的方式解释和执行除罪化。这些发现对考虑药物政策改革的政策制定者和警察领导层具有重要意义。官员感到权力被剥夺和政策无意义,特别是在法律含糊不清的情况下,可能导致执法不一致或不公平。加强警察队伍之间的沟通至关重要。中层管理者可以帮助转化改革目标,识别资源缺口,并支持有效的应对策略。法律的明确性不应局限于政策更新,而应帮助官员协调重叠的法律,并减少对责任的担忧。虽然在警察机构的等级结构中,与一线警官进行政策咨询是有限的,但改革努力仍应考虑到一线警官的工作逻辑。培训应解决对药物使用的有害态度和误解,澄清法律界限,减轻执法造成的意外伤害。最终,在多司法管辖区系统中,有效的毒品政策改革需要承认一线官员如何在制度约束下解释和制定政策。

Research Summary

Street crimes are thought to be influenced by changes in ambient lighting; yet, most studies have focused on small-scale interventions in limited areas. It remains unclear whether enhanced lighting can improve safety on a larger, jurisdiction-wide scale. This study examined the first 10 months of Philadelphia's citywide rollout of enhanced street lighting. Between August 2023 and May 2024, 34,374 streetlights were upgraded across 13,275 street segments, converting roughly one third of the city's street segments to new LED (light-emitting diode) fixtures that provide clearer and more even lighting. We assessed the impact of these upgrades on total crimes, violent crimes, property crimes, and nuisance crimes. Our findings reveal a 15% decline in outdoor nighttime street crimes and a 21% reduction in outdoor nighttime gun violence following the streetlight upgrades. The streetlight upgrades may have contributed to 5% of the citywide decline in Philadelphia gun violence during the study period. Qualitative data also suggest that resident perceptions of safety and neighborhood vitality improved after new streetlights were installed.

Policy Implications

Although prior research has mostly focused on small-scale implementations, our study demonstrates that improvements in street lighting can significantly reduce crime rates across large urban areas. These results support the adoption of energy-efficient LED street lighting as a crime reduction strategy for cities. Further research is needed to explore the impact of enhanced streetlight interventions on other types of crime and to determine whether the crime reduction benefits are sustained when these upgrades are implemented across the entire City of Philadelphia for an extended period.

研究总结:街头犯罪被认为受到环境照明变化的影响;然而,大多数研究集中在有限地区的小规模干预措施上。目前还不清楚增强照明是否能在更大范围内提高交通安全。这项研究调查了费城在全市范围内推广增强街道照明的前10个月。在2023年8月至2024年5月期间,在13,275个街道段中升级了34,374盏路灯,将大约三分之一的城市街道段转换为新的LED(发光二极管)灯具,提供更清晰,更均匀的照明。我们评估了这些升级对总犯罪、暴力犯罪、财产犯罪和滋扰犯罪的影响。我们的研究结果显示,在路灯升级之后,户外夜间街头犯罪减少了15%,户外夜间枪支暴力减少了21%。在研究期间,路灯升级可能对费城全市枪支暴力下降的5%做出了贡献。定性数据还表明,安装新路灯后,居民对安全和社区活力的看法有所改善。政策影响虽然先前的研究主要集中在小规模的实施上,但我们的研究表明,改善街道照明可以显著降低大城市地区的犯罪率。这些结果支持采用节能LED街道照明作为城市减少犯罪的策略。需要进一步的研究来探索加强路灯干预对其他类型犯罪的影响,并确定当这些升级在整个费城实施一段较长时间后,减少犯罪的好处是否持续。

BackgroundMexico rolled out state‐led criminal justice reforms between 2000 and 2017 to modernize procedures and improve rule of law.

墨西哥在2000年至2017年期间推行了国家主导的刑事司法改革,以实现程序现代化并改善法治。这些变化是否减少了暴力犯罪,特别是在受贩毒集团影响的地区,仍不确定。目的评估改革实施对杀人和逮捕的影响,并评估与执法能力和公众与执法部门合作有关的机制。材料和方法我们根据死亡证明(凶杀案)和行政记录(逮捕)建立了一个市政年度面板(2000-2017)。由于各州在不同的时间采取了改革,我们使用了为交错采用和异质处理效果而设计的差中差估计器,具有丰富的固定效果和控制。为了探究机制,我们分析了具有全国代表性的犯罪报告、机构信任和感知警察/检察官廉正的调查措施。结果改革的实施与凶杀率增加了25%有关。在同一时期,逮捕率下降了50%。由于凶杀案不像其他犯罪那样容易漏报,凶杀案的增加不太可能是虚假的报告。调查证据显示,犯罪报告减少,对机构的信任度下降,对警察和检察官的负面看法增加;在受卡特尔影响的地区,影响最为严重。这种模式与有效执法能力的削弱是一致的:更少的逮捕和更低的公众合作提高了暴力犯罪的预期回报。在高暴力环境中,改革程序而不同时提高调查和起诉能力,也不保障证人,会削弱威慑力。结论:墨西哥错开的司法改革伴随着更高的谋杀率和更低的逮捕率。暴力背景下的成功改革可能需要协调一致的机构加强(警务、起诉、证人保护),以可衡量的基准分阶段实施,以及维持公众信任和报告的战略。

Research Summary

Since 2018, at least 12 U.S. states have introduced policies to expunge certain eligible arrest and criminal conviction records through automated or algorithmic means. Drawing on interviews with governmental representatives and community stakeholders, this paper identifies strategies used to pass this legislation in Pennsylvania and Utah, the first two states to enact automated expungement policies. We frame our findings around three established theoretical frameworks of public policy making—policy entrepreneurship, issue framing, and coalition building—illustrating their combined strategic importance with data gathered from those involved on the ground in the passage and adoption of automated expungement legislation. The findings add depth and nuance to the policy-making literature, along with practical implications for future criminal legal reform initiatives.

Policy Implications

Interviewees consistently described how key policy entrepreneurs played essential roles in the development, passage, and implementation of automated criminal record expungement by strategically framing the issue of criminal record discrimination around core values shared by conservatives and liberals, such as workforce development. Broad bipartisan coalition building enabled the scale-up of automated expungement policies within states where it has been adopted and has aided diffusion to new states. These findings can inform the approaches taken by advocates of automated expungement and other criminal justice reform initiatives, particularly in conservative or polarized political environments.

自2018年以来,美国至少有12个州出台了通过自动或算法手段删除某些符合条件的逮捕和刑事定罪记录的政策。通过对政府代表和社区利益相关者的访谈,本文确定了宾夕法尼亚州和犹他州通过该立法的策略,这两个州是最早制定自动删除政策的两个州。我们围绕公共政策制定的三个既定理论框架(政策企业家精神、问题框架和联盟建设)构建了我们的研究结果,并通过从参与通过和采用自动删除立法的人那里收集的数据,说明了它们的综合战略重要性。研究结果为政策制定文献增加了深度和细微差别,同时也为未来的刑事法律改革举措提供了实际意义。政策影响受访者一致地描述了关键政策企业家如何在犯罪记录自动删除的开发、通过和实施中发挥重要作用,方法是围绕保守派和自由派共同的核心价值观(如劳动力发展)战略性地构建犯罪记录歧视问题。广泛的两党联盟的建立使自动删除政策在已经采用的州内扩大规模,并有助于向新的州扩散。这些发现可以为自动删除和其他刑事司法改革倡议的倡导者所采取的方法提供信息,特别是在保守或两极分化的政治环境中。

Research Summary

Closed-circuit television (CCTV) video surveillance cameras and gunshot detection technology (GDT) have been widely adopted by police departments in recent years. Most evaluation research on CCTV and GDT has tested the technologies’ effect on crime prevention rather than case clearance rates. The current study contributes to the literature through a matched quasi-experiment of the relative and joint effect of GDT and CCTV on fatal and nonfatal shooting investigation outcomes in Chicago, IL. Entropy balancing is used to create a weighted control group that closely resembles the treatment group. Logistic regression models incorporating the weights from the entropy matching procedure as probability weights measure the intervention effects. Treatment conditions generated null findings across all models. Although included as a control variable in the models, Chicago's Strategic Decision Support Centers (SDSCs) were positively associated with case clearance in the nonfatal shooting models.

Policy Implications

These findings contribute to the knowledge base on police use of technology in gun violence investigations. Similar to prior research, results indicate that technology may not deliver the crime control benefits policy makers anticipate they will receive from their investments. Gun violence represents the United States’ most critical crime problem, with the decrease in clearance rates garnering significant attention in both the academic and practitioner communities. The current study suggests that investments in technology on their own may not directly improve case clearance rates. However, the findings regarding SDSCs indicate they may be a promising model for leveraging the outputs of multiple technologies to assist gun violence investigations. Increased resources should be dedicated to rigorously testing the effect of SDSCs on gun violence investigation outcomes.

近年来,闭路电视(CCTV)视频监控摄像机和枪炮探测技术(GDT)被警察部门广泛采用。大多数关于CCTV和GDT的评估研究都测试了这些技术对预防犯罪的影响,而不是案件破案率。目前的研究通过一个匹配的准实验,对伊利诺伊州芝加哥致命和非致命枪击调查结果的GDT和CCTV的相对和联合效应进行了贡献。熵平衡用于创建一个与治疗组非常相似的加权对照组。采用熵匹配过程的权重作为概率权重的逻辑回归模型衡量干预效果。在所有模型中,治疗条件均未产生任何结果。尽管在模型中作为控制变量,芝加哥的战略决策支持中心(SDSCs)在非致命枪击模型中与案件清除率呈正相关。这些发现有助于建立警察在枪支暴力调查中使用技术的知识库。与先前的研究类似,结果表明,技术可能不会带来政策制定者预期的从投资中获得的控制犯罪的好处。枪支暴力是美国最严重的犯罪问题,清除率的下降引起了学术界和实务界的极大关注。目前的研究表明,对技术本身的投资可能不会直接提高案件清除率。然而,关于sdsc的研究结果表明,它们可能是一种很有前途的模式,可以利用多种技术的产出来协助枪支暴力调查。应增加资源,严格测试sdsc对枪支暴力调查结果的影响。

Research Summary

We evaluated the impact of an administrative order issued in the early days of the coronavirus disease 2019 (COVID-19) pandemic that aimed to reduce the size of the pretrial population in Palm Beach County, FL, by reducing bond amounts for eligible felony offenses. Our findings revealed that the administrative order was successful in reducing the average bond amounts for individuals charged with eligible felonies and that these reductions corresponded to (1) increases in the likelihood of pretrial release and (2) declines in the average custody length. Furthermore, despite these changes to the odds and pace of pretrial release, we found no evidence to suggest that the administrative order negatively affected pretrial compliance, including new criminal activity and failure to appear in court.

Policy Implications

The COVID-19 pandemic set in motion a range of policy changes to mitigate virus spread within correctional facilities, recognizing the vulnerabilities of correctional environments and incarcerated persons. These changes resulted in immediate reductions to jail populations. However, questions quickly emerged regarding their impacts on public safety, among other considerations. The current investigation evaluated the effect of one such COVID-19 era policy shock on pretrial detention and misconduct. Our findings revealed that reducing bond amounts for individuals charged with eligible felonies contributed to increased rates of pretrial release and reduced detention lengths without jeopardizing either public safety or court efficiency. Consistent with other recent pretrial research, these findings suggest that by reducing our reliance on money bail, we can reduce financial barriers to release among justice-involved populations, ease inefficiencies in the courts, and save scarce jail resources by scaling back unnecessary pretrial detention. As the pandemic recedes, evaluations of COVID-19 era policies can help provide a framework for promising criminal justice reforms that reduce our overuse of incarceration and help contribute to a fair and impartial system.

研究摘要:我们评估了2019年冠状病毒病(COVID - 19)大流行初期发布的一项行政命令的影响,该命令旨在通过减少符合条件的重罪犯罪的保释金来减少佛罗里达州棕榈滩县审前人口的规模。我们的研究结果显示,行政命令成功地减少了被指控犯有符合条件的重罪的个人的平均保释金数额,并且这些减少对应于(1)审前释放可能性的增加和(2)平均拘留时间的减少。此外,尽管审前释放的几率和速度发生了这些变化,但我们没有发现证据表明行政命令对审前合规产生了负面影响,包括新的犯罪活动和未能出庭。政策影响新冠肺炎疫情引发了一系列政策变化,以减轻病毒在惩教设施内的传播,同时认识到惩教环境和在押人员的脆弱性。这些变化导致监狱人口立即减少。然而,关于它们对公共安全的影响等问题迅速浮出水面。目前的调查评估了一次这样的COVID - 19时代政策冲击对审前拘留和不当行为的影响。我们的研究结果显示,减少被指控犯有重罪的个人的保释金数额有助于提高审前释放率,缩短拘留时间,而不会危及公共安全或法庭效率。与最近的其他审前研究一致,这些研究结果表明,通过减少对保释金的依赖,我们可以减少司法相关人群释放的经济障碍,缓解法院的低效率,并通过减少不必要的审前拘留来节省稀缺的监狱资源。随着疫情的消退,对COVID - 19时代政策的评估有助于为有希望的刑事司法改革提供框架,减少我们过度使用监禁,并有助于建立公平和公正的制度。
