On the evening of May 10, 2019, near Monroe, Louisiana, a Louisiana State Police trooper tried to stop a 49-year-old Black man named Ronald Greene for speeding and running a red light. Mr. Greene drove away. For 14 minutes, officers pursued him until he lost control of his vehicle, crashing on the side of the road. According to a sergeant that LSP regarded as its in-house use-of-force expert, what happened in the ensuing hours, weeks, and months was a “catastrophic failure in a million different directions.” Multiple LSP troopers and sheriff’s deputies arrived at the scene of the crash. They tased Mr. Greene repeatedly and pulled him out of his car. They punched him, dragged him by ankle shackles, and left him face down in the road. When Mr. Greene tried to roll onto his side, a trooper put his foot on Mr. Greene’s buttocks to hold him down on his stomach. That trooper later told a supervisor, “I’m trying to keep him laying down. I was going to sit him up, but I don’t want him spitting blood all over us.” Mr. Greene pleaded, “I’m scared. I’m your brother. I’m scared.” The LSP troopers deactivated or muted their body-worn cameras. When a supervisor arrived, he casually stepped over Mr. Greene, who laid moaning on the ground, and instead asked the troopers if they were ok. None of the troopers rendered aid to Mr. Greene, who became unresponsive and died before he reached the hospital. After Mr. Greene died, troopers filed reports attributing his death to a car accident. “We investigate crashes every day,” one trooper later told us. “No way someone died from a car crash with that damage.” One trooper who was there misdated the incident in an official report. LSP’s designated use-of-force expert at the time believed that was a deliberate attempt to cover up the incident. Another trooper miscategorized camera footage in LSP’s systems. And the supervisor who stepped over Mr. Greene’s body that night signed off on all the use-of-force reports. Over 15 months passed before LSP opened an Internal Affairs investigation into Mr. Greene’s death. In the intervening days and months, LSP troopers—including one involved in Mr. Greene’s death—would go on to assault more drivers. It was not until September 2020, 16 months after the incident, that LSP fired one of the troopers involved. It would take until 2021 for LSP to suspend a second trooper and fire a third who was involved in both Mr. Greene’s death and an assault of a different Black man. Mr. Greene’s death and its aftermath demonstrated serious failures at LSP—excessive force, improper supervision, ineffective training, and breakdowns in accountability. As our civil pattern or practice investigation revealed, these failures were not isolated, but part of a larger pattern or practice of law enforcement conduct that deprives people in Louisiana of their rights under the Constitution.

Following a comprehensive investigation, the Department of Justice has reasonable cause to believe that the Louisiana State Police engage in a statewide pattern or practice of using excessive force, which violates the Fourth Amendment. Our investigation, opened in 2022, also included examining whether LSP engages in racially discriminatory policing. At this time, we make findings only as to excessive force. Though this investigation reveals systemic problems, we recognize that most LSP troopers work hard to keep the public safe. We commend LSP troopers and staff who devote their professional lives to serving the community. LSP began making much-needed reforms after video of Mr. Greene’s death became public in 2021, two years after the incident. We believe those changes may have contributed to some recent improvements in use-of-force practices. The changes include revising LSP’s use-of-force policy, creating a Force Investigation Unit to investigate serious uses of force, and updating training programs. However, more reforms are needed to remedy the unlawful conduct we found. We describe recommended changes at the end of this report. We hope to work constructively with the State and LSP to implement these reforms.

Incidents of police-involved shootings resulting in the death of unarmed civilians, such as Andre Hill in 2020, Bijan Ghaisar in 2017, and Michael Brown in 2014, have raised concerns about law enforcement use of deadly force, particularly involving firearms. In light of these concerns, growing attention has been paid to less-than-lethal weapons (LLWs) and the role LLWs may play in providing law enforcement officers alternatives to the use of deadly force.

A multitude of weapons marketed as less-than-lethal alternatives to firearms are currently in use by federal, state, and local law enforcement, including batons, pepper sprays, and stun guns. There are also a number of LLWs in development, such as unmanned aircraft systems (drones) equipped with tear gas, rubber bullets, and TASERs.

Some observers contend that LLWs offer the possibility of minimizing risk of death and serious injury to citizens and officers while simultaneously providing law enforcement with effective tools to incapacitate violent or noncompliant persons. Nevertheless, there is evidence that LLWs may present a number of potential health risks, lending credence to arguments that LLWs are less-than-lethal in name, but, depending on the circumstances of their use, can be lethal in practice. For example, a team of journalists led by the Associated Press, in collaboration with the Howard Center for Investigative Journalism programs at the University of Maryland and Arizona State University, documented over 1,000 deaths that followed local and state police officers’ use of less-than-lethal force from 2012 to 2021. Similarly, a 2019 Reuters investigation of deaths related to law enforcement use of TASERs found that 1,081 individuals had died after being hit by a police TASER from 1983 to 2017.

Should policymakers consider examining ways to legislate on the use of LLWs, numerous issues may garner attention. Currently, there is no single, universally accepted definition of less-than-lethal weapon, and the use of the term varies greatly among U.S. federal, state, and local law enforcement agencies. Conceptualizing a definition for LLWs raises a number of questions, including whether LLWs should be defined

• under a label other than less-than-lethal,

• according to a common capability,

• according to a common operational utility,

• according to an intended use to minimize risk of death and permanent injury, or

• according to a common application.

Policymakers could consider whether it is beneficial to establish a statutory definition of less-than-lethal weapon. Codifying the meaning of LLWs could be useful in terms of clarifying what weapons are (and are not) classified as less-than-lethal, which may help sharpen the focus and potential efficacy of policies. On the other hand, some may argue that law enforcement agencies and departments are better suited to define LLWs and, thereby, address LLWs in their individualized use-of-force policies, based on their organization’s specific needs, duties, and circumstances.

Moreover, there are relatively little federal data available on law enforcement officers’ use of LLWs and, consequently, few studies analyzing the health effects caused by law enforcement’s use of such weapons. Policymakers may wish to direct a federal agency or department to conduct research into LLW injury and mortality. Based on these findings, policymakers could consider legislative actions to influence law enforcement use of LLWs, such as (1) passing a bill encouraging or limiting federal law enforcement officers’ usage of LLWs and (2) placing provisions on or withholding funding from existing federal grant programs to incentivize or discourage state and local law enforcement usage of LLWs.

An underlying premise of democratic politics is that protest can be an effective form of civic engagement that shapes policy changes desired by marginalized groups. But it is not certain that this premise holds up under scrutiny. This paper presents a three-part argument that protest (a) signals the salience of a movements’ focal issue and expands awareness that an issue is a social problem requiring a solution, (b) empowers residents in disadvantaged communities and raises a sense of community cohesion, which together (c) raise costs and exert pressure on elites to make concessions. The empirical analysis examines the likelihood that a city will establish a Civilian Review Board (CRB). It then compares the effects of protest and CRB presence on counts of officer-involved fatalities by race and ethnicity. Two main conjectures about the effect of protest are supported: Cities with more protest against police brutality are significantly more likely to establish a CRB, and protest against police brutality reduces officer-involved fatalities for African Americans and Latinos (but not for Whites). But the establishment of CRBs does not reduce fatalities, as some have hoped. Nonetheless, mobilizing against police brutality matters, even in the absence of civilian review boards.

Every year Campaign Zero works to make this data accessible and understandable to the public via Mapping Police Violence, a platform tracking civilians killed by U.S. law enforcement. This report aims to provide key takeaways concerning incidents of police violence that resulted in a civilian being killed in 2024. Mapping Police Violence relies on local journalism, and sources news through our system which collects, filters, and processes the data. While we strive to employ official data sources from local and state government agencies, we believe it is important to continue collecting data from publicly accessible media sources. This allows us to identify gaps in government data, and further triangulate and validate the data. As per our methodology, all incidents go through a multi-layered review process. It is likely that the number of incidents may increase in the coming months because some police killings and their circumstances are not reported until weeks or months later.

Objective. The purpose of this article is to examine the relationship between mother–youth closeness and stigma stemming from police contact. Background. Research increasingly indicates that stigma stemming from police–youth encounters links police contact to compromised outcomes among youth, though less is known about the correlates of stigma stemming from this criminal legal contact. Close mother–youth relationships, commonly understood to be protective for youth outcomes, may be one factor that buffers against stop-related stigma, especially the anticipation of stigma. Method. We use data from the Fragile Families and Child Wellbeing Study, a sample of youth born in urban areas around the turn of the 21st century, to examine the relationship between mother–youth closeness and stop-related stigma. Results. We find that mother–youth closeness is negatively associated with stop-related anticipated stigma but not stop-related experienced stigma. We also find that the relationship between mother–youth closeness and stop-related anticipated stigma is concentrated among youth experiencing a non-intrusive stop. Conclusion. Close mother–youth relationships may protect against stigma stemming from criminal legal contact.

Research shows youth police contact— a stressor experienced by more than one-quarter of urban-born youth by age 15—has deleterious mental health consequences for both youth and their mothers. Less is known about how youth’s fathers respond to this police contact, despite differences in how men and women respond to stress and relate to their children. I use data from the Fragile Families and Child Wellbeing Study to investigate the association between youth police stops and depression among youth’s fathers. Results show that fathers of youth stopped by the police, compared to fathers of youth not stopped by the police, are more likely to report depression, net of father and youth characteristics associated with selection into experiencing youth police stops. This association is concentrated among non-Black fathers and fathers of girls. The findings highlight how the repercussions of youth criminal legal contact extend to youth’s fathers and, more broadly, suggest that future research incorporates the responses of men connected to those enduring criminal legal contact.

Objective. The goal of this study is to examine the association between parental incarceration and parent–youth closeness. Background. Despite the established complex repercussions of incarceration for relationships between adults, and the well-known intergenerational consequences of parental incarceration, little is known about how incarceration structures intergenerational relationships between parents and children. Methods. In this article, I use data from the Future of Families and Child Wellbeing Study (N = 3408), a cohort of children followed over a 15-year period, to examine how parental incarceration is associated with relationships between youth and their (incarcerated and non-incarcerated) parents. Results. Results suggest three conclusions. First, parental incarceration is negatively associated with closeness between youth and their incarcerated parents. Second, the timing of first parental incarceration is important. Parental incarceration in early or middle childhood is negatively associated with closeness between youth and their incarcerated parent, and parental incarceration in adolescence is positively associated with closeness between youth and their non-incarcerated parent. Third, relationships between parents themselves explain some of the association between paternal incarceration in early childhood and father–youth closeness. Conclusion. Taken together, these findings advance our understanding of both the relational and intergenerational consequences of criminal legal contact and our understanding of the correlates of parent–youth relationships and, in doing so, highlights how family ecological contexts contribute to inequality.

 A family systems perspective suggests the repercussions of adolescent police contact likely extend beyond the adolescent to proliferate to the broader family unit, but little research investigates these relationships. I used data from the Fragile Families and Child Wellbeing Study, a longitudinal survey of children who became adolescents during an era of proactive policing, to examine the relationship between adolescent police contact and four aspects of family life: mothers’ parenting stress, mothers’ monitoring, mothers’ discipline, and the mother-adolescent relationship. Adolescent police contact, especially invasive police contact, is associated with increased parenting stress, increased discipline, and decreased engagement, net of adolescent and family characteristics that increase the risk of police contact. There is also evidence that suggests adolescent police contact is more consequential for family life when mothers themselves had experienced recent police contact. These findings suggest the repercussions of police contact extend beyond the individual and proliferate to restructure family relationships.

Police stops are a pervasive form of criminal justice contact among adolescents, particularly adolescents of color, that have adverse repercussions for mental health. Yet, the mental health consequences of adolescent police stops likely proliferate to parents of adolescents exposed to this form of criminal justice contact. In this article, I conceptualize adolescent police stops as a stressor, drawing on the stress process perspective to examine how and under what conditions this form of criminal justice contact damages the mental health of adolescents’ mothers. The results, based on data from the Fragile Families and Child Wellbeing Study, suggest three conclusions. First, the mental health consequences of adolescent police stops proliferate, increasing the likelihood of depression and anxiety among adolescents’ mothers. These relationships persist across modeling strategies that adjust for observed confounders, including adolescent characteristics such as delinquency and substance use. Second, the relationship between adolescent police stops and mothers’ mental health is contingent, concentrated among mothers with prior exposure to the criminal justice system (either via themselves or their adolescents’ fathers). Third, mothers’ emotional support buffers the relationship between adolescent police stops and mothers’ mental health. Taken together, this research highlights the role of police exposure as a stressor that is experienced vicariously and that has contingent consequences and, accordingly, documents the expansive and proliferating repercussions of police contact. Given the concentration of police contact among marginalized adolescents, including adolescents of color, these findings highlight another way the criminal justice system exacerbates structural inequalities.

Social vulnerability, race, and place are three important predictors of fatal police shootings. This research offers the first assessment of these factors at the zip code level. Methods: The 2015−2022 Mapping Police Violence and Washington Post Fatal Force Data (2015 −2022) were used and combined with the American Community Survey (2015−2022). The social vulnerability index (SVI) was computed for each zip code by using indicators suggested by CDC, then categorized into low-, medium-, and high-SVI. The analytical file included police officers who fatally shot 6,901 individuals within 32,736 zip codes between 2015 and 2022. Negative Binomial Regression (NBRG) models were run to estimate the association between number of police shootings and zip code SVI, racial composition, and access to guns using 2015-2022 data. Results: Moving from low-SVI to high-SVI revealed the number of fatal police shootings increased 8.3 times, with the highest increases in Blacks (20.4 times), and Hispanics (27.1 times). The NBRG showed that moderate-, and high-SVI zip codes experienced higher fatal police shootings by 1.97, and 3.26 times than low-SVI zip codes; zip code racial composition, working age population, number of violent crimes, number of police officers and access to a gun, were other predictors of fatal police shootings. Conclusions: Social vulnerability and racial composition of a zip code are associated with fatal police shooting, both independently and when considered together. What drives deadly police shootings in the United States is not one single factor, but rather complex interactions between social-vulnerability, race, and place that must be tackled synchronously. Action must be taken to address underlying determinants of disparities in policing.

The City of Los Angeles Mayor’s Office of Gang Reduction and Youth Development (GRYD) program was conceived as a comprehensive response to gang violence. Unlike most comprehensive approaches, suppression was excluded from the primary model. Program services including community engagement, gang prevention and intervention services, and street-based violence interruption, were formally launched in late 2011. Strict geographic eligibility criteria mean that GRYD services were available in some Los Angeles communities and not others. Using the geographic structure of GRYD, we use a place-based difference-in-differences model to estimate the effect of GRYD services on both violent and property crime. The analyses suggest a reduction in violent crime of around 18% in areas exposed to GRYD Comprehensive Strategy services, including aggravated assault and robbery. Similar declines are not observed in property crimes including burglary and car theft. Comparison with evaluations of placed-based gang injunctions demonstrate that GRYD is able to achieve nearly one-half of the reductions in crime without a suppression focus.

Nighttime activities have significantly increased in cities, underscoring the growing importance of nocturnal lighting in fostering emotional stability and comfort of people. This study utilized simulated virtual reality (SVR) technologies to investigate the relationship between lighting environment and fear of crime in narrow residential streets. We created virtual models replicating a typical low-rise residential area in Seoul, Korea, diversified into eight environments representing different times of day with corresponding lighting scenarios (natural light, streetlamps, and interior building lights). One hundred recruited young adult participants were asked to experience four randomly selected environments and rate their perceived level of fear of crime while wearing a head-mounted display. The ordinal logistic regression analysis demonstrated that fear of crime was influenced not only by natural light but also significantly by artificial lights on streets and inside buildings.

Specifically, while a decrease in natural illuminance contributes to an increase in fear of crime in general (especially shortly after sunset), the role of natural illuminance was minimized immediately after streetlamp activation. After p.m. 8:30, when other light sources are relatively constant, fear of crime was significantly influenced by the proportion of interior building lights turned on. In residential areas where preventing light pollution is also crucial, a comprehensive strategy is necessary rather than solely focusing on improving illuminance levels to create safe and comfort lighting environment

Racial Disparities in Arrests in Santa Clara County, California, 1980

By Sophia Hunt, Micayla Bozeman, and Matthew Clair

This report examines racial/ethnic disparities in arrests in Santa Clara County, California, from 1980 to 2019. Over the past forty years, felony and misdemeanor arrest rates have declined for all racial groups, but racial disparities have persisted and, in some cases, increased. Black residents, though a small percentage of the population, are disproportionately susceptible to being arrested. In the 2010s, the Black arrest rate was 5.4 times the White arrest rate—the highest BlackWhite ratio in arrest rates observed over the four decades. Nevertheless, as overall arrest rates declined over this period, the absolute difference between Black and White arrest rates substantially narrowed. Hispanic residents are also disproportionately arrested, but to a lesser degree than Black residents. Racial/ethnic disparities are most pronounced with respect to felony arrests; the Black-White ratio in felony arrest rates peaked at 7.2 in the 1980s and declined to 6.6 in the 2010s. Racial/ethnic disparities also exist, to a lesser degree, with respect to misdemeanor arrests. We find small racial differences in arrest dispositions (or, what law enforcement does with a person following arrest). However, it is noteworthy that, across all four decades, Black and Hispanic felony arrests are slightly more likely than White felony arrests to result in release due to “insufficient grounds to file a complaint.” This pattern could suggest that law enforcement officers are more likely to arrest Black and Hispanic residents for reasons that law enforcement entities later determine do not rise to the level sufficient for filing a complaint with the District Attorney’s Office.

Broader public, media, and scholarly interest in police shootings of residents in the United States has been a constant since 2014. This interest followed a number of high-profile deadly force incidents, including those leading to the deaths of Michael Brown in Ferguson, MO, and Tamir Rice in Cleveland, OH. In the decade since, researchers from a variety of academic disciplines have learned much about the scope and nature of police shootings. While US police as a whole use their firearms more than most other countries, rates of police shootings of residents vary across states.

The purpose of this report is to examine police shootings of residents—including both fatal and nonfatal, injurious incidents—using a comparative lens. More specifically, it explores rates of police shootings in the states comprising the Regional Gun Violence Research Consortium (RGVRC)—Connecticut, Delaware, Massachusetts, New Jersey, New York, Pennsylvania, and Rhode Island—with the rest of the country. These comparisons suggest an association between levels of firearm prevalence/availability in the general population, as well as related laws and rates of police shootings per capita. The majority of RGVRC states possess the lowest rates of police shootings of residents, which appears to at least partially be a function of low levels of firearm prevalence/availability among residents and strong laws and legislation related to guns.

In the spring of 2020, the pandemic sealed borders and blinded those monitoring human rights violations along the Bosnian-Croatian border. Amid this backdrop, the Croatian authorities seemingly believed they could act with impunity. They were mistaken. NNK’s team activated its local network, connecting with neighbors to identify illegal pushbacks. On May 6th, in Poljana, Bosnia, sources reported a group of people had been forcibly returned, their heads marked with orange crosses. The men had their money, shoes, and mobile phones stolen. The use of spray paint –a religious symbol forced onto these predominantly Muslim men– suggests a disturbing mix of humiliation and psychological warfare. This case marked the beginning of a series of pushbacks involving an alarming level of torture and sadism, disconnected from any genuine border protection or respect for fundamental human rights. Croatian and European authorities have long justified pushbacks, citing bilateral agreements that bypass judicial due process and International Law. Likewise, the use of coercive force has been also legitimized under the guise of maintaining order. However, painting someone’s head with spray paint is neither defensible, legal, nor ethical, as it is robbing people of their phones, shoes, glasses, medicines, and passports and then burning these items in pyres. This is exactly what is happening today. Between October 2023 and August 2024, NNK conducted an extensive field investigation, uncovering evidence of these “burn piles”– secret locations where Croatian border police destroy the personal belongings of people attempting to migrate for a better life. This report compiles the evidence, survivor testimonies, and details the systematic and brutal modus operandi, aiming to push the Croatian administration towards accountability while urging European authorities and civil society to reflect on why would a border agent feel justified in taking a pair of glasses from a teenager fleeing war, leaving him blind in a forest at night, and then tossing those glasses into the flames to convert his hope into ashes? This border regime fails: it punishes the innocent while granting impunity to the undeserving. It is time to react. Time for safe and dignified routes.

Despite evidence of gradually declining rates of violent crime over the last several decades, violence continues to pose a serious problem for many urban communities (Federal Bureau of Investigation, 2018). Indeed, recent trends in violent crime within the United States suggest violence is a chronic problem, producing substantial costs to communities and individuals, and requiring immediate response from a coalition of stakeholders. As such, finding effective interventions to target violence is essential for restoring communities and enhancing public health and safety. This literature review examines the available empirical evidence on a variety of police-led violence reduction strategies (offender-focused, place-based, and community-based), as well as community-led, public health-based violence prevention interventions. The purpose of this review is to summarize for practitioners, policymakers, and researchers the state of the evidence regarding the effectiveness of various approaches to reduce violence, highlight implications for practice (see Appendix A), and identify the remaining gaps in this knowledge needing to be addressed by future research.

Critics of American policing often make the claim that it is a direct descendant of antebellum slave patrols, the mostly voluntary groups organized to capture runaway slaves and stifle slave rebellions in the early eighteenth century. Consider just a few examples:

• “The origins of modern-day policing can be traced back to the ‘Slave Patrol.’” — NAACP

• “Policing itself started out as slave patrols. We know that.” — Rep. James Clyburn.

• “Slave patrols . . . morphed directly into police.” — Nikole HannahJones.

• “[M]odernized police actually emerged in the South during slavery— they literally were slave catchers.” — Scalawag Magazine.

Even pro-law enforcement organizations such as the National Law Enforcement Memorial and Museum in Washington, D.C. have come to accept this claim. According to one criminal justice textbook, it is “widely recognized that law enforcement in the 20th-century South evolved directly from these 18th and 19th-century slave patrols.”

While it is true that slave patrols were a form of American law enforcement that existed alongside other forms of law enforcement, the claim that American policing “traces back” to, “started out” as, or “evolved directly from,” slave patrols, or that slave patrols “morphed directly into” policing, is false. This widespread pernicious myth falsely asserts a causal relationship between slave patrols and policing and intimates that modern policing carries on a legacy of gross injustice. There is no evidence for either postulate.

In order to demonstrate causation, one must show that modern policing drew its distinctive practices and structure from slave patrols. But the evidence shows that American law enforcement—whether in the form of sheriffs, town watches, constables, or police—all emerged from distinctly English influences. Both slave patrols and modern police departments drew from these influences. The fact that the latter did so after the former does not mean that the latter emerged from the former.

Community Violence Can Be Prevented All people want to be healthy, safe, and connected to other people. We all want to have access to life opportunities, including education and employment, to become valued members of communities and society, and to live our lives free from violence. To support community violence prevention and promote health and safety, the Division of Violence Prevention (DVP) in the National Center for Injury Prevention and Control (NCIPC) at the Centers for Disease Control and Prevention (CDC) developed the Community Violence Prevention Resource for Action (or Prevention Resource, for short). DVP’s vision is to have a violence-free society in which all people and all communities are safe, healthy, and thriving. Violence is preventable using a public health approach. This includes bringing together partners and community members to consider local needs and the best available evidence to implement violence prevention strategies. About this Prevention Resource for Action Community violence happens in public places, such as streets or parks, between people who may or may not know each other. Examples include assaults, fights among groups, homicides, and fatal and nonfatal shootings. This resource is informed by research and conversations with community members, people who have experienced violence, and other partners.a It is an update to the Youth Violence Prevention Resource for Action.  It includes evidence for preventing violence experienced by youth (ages 10-24), which is now under the larger community violence topic. In this update, we expand the evidence to include examples for preventing violence experienced by young adults (ages 25-34). Young adults ages 20-24 have the highest homicide rate. They are closely followed by young adults between the ages of 25-29, 30-34, and then teens ages 15-19.8 Over the past 40 years, we have learned a lot about preventing violence, but there is still more work to do. This resource is intended to help communities and states prevent violence before it starts and lessen the harms of violence that occur by describing the best available evidence for community violence prevention. DVP looks forward to learning from communities and states about how this resource is being used and how it can be improved so that all communities are safe, healthy, and thriving. This Prevention Resource has three components. The first component is the strategy, or the direction or actions needed to prevent community violence. The second component is the approach, or specific ways to advance the strategy through policies, programs, or practices. The third component is the evidence for each approach in preventing community violence or the conditions or behaviors that increase risk for community violence. The examples provided in this resource are not intended to be a comprehensive list of evidence-based programs, policies, or practices for each approach. Rather, they illustrate models that have been shown to prevent community violence or impact conditions or behaviors that increase risk or protect against violence

Aim: To examine the long-term effect of two routine police activities on property and violent crime in NSW.

Method: Police move-on directions and person searches as well as property and violent crimes were extracted from the NSW Police Force’s Computerised Operational Policing System. We investigate the relationship between police activity and crime using panel of 17 Local Area Commands (LACs) over the period 2001 to 2013. To estimate the long-run relationship, panel models of Pooled Mean Group and Mean Group were applied to allow for differing effects between LACs.

Results: We estimated a significant and strongly negative long-run relationship between both indices of police activity (move-on directions and person searches) and each of break and enter, motor vehicle theft and robbery. The person search activity is negatively related to assault, but the effect is weak; with a 10 per cent increase in person searches only producing a 0.29 per cent fall in assaults. No significant long-run relationship was found between assault and move-on directions.

Conclusion: Sustained increases in police activity, whether in the form of move-on directions or person searches, do appear to help suppress break and enter, motor vehicle theft and robbery but do not appear to help in reducing assault.

 We describe and apply three empirical approaches to identify superfluous police activity, unjustified racially disparate impacts, and limits to regulatory interventions. First, using cost-benefit analysis, we show that traffic and pedestrian stops in Nashville and New York City disproportionately impacted communities of color without achieving their stated public safety goals. Second, we address a longstanding problem in discrimination research by presenting an empirical approach for identifying “similarly situated” individuals and, in so doing, quantify potentially unjustified disparities in stop policies in New York City and Chicago. Finally, taking a holistic view of police contact in Chicago and Philadelphia, we show that settlement agreements curbed pedestrian stops but that a concomitant rise in traffic stops maintained aggregate racial disparities, illustrating the challenges facing regulatory efforts. These case studies highlight the promise and value of viewing legal principles and policy goals through the lens of modern data analysis—both in police reform and in reform efforts more broadly.
