Racial disparities have long pervaded every step of the criminal justice process, from police stops, searches, arrests, shootings an the country, federal, state, and local governments are doing far too little to proactively identify them, report their behavior to prosecutors who might unwittingly rely on their testimony in criminal cases, or protect the diverse communities they are sworn to serve.

Efforts to address systemic and implicit biases in law enforcement are unlikely to be effective in reducing the racial disparities in the criminal justice system as long as explicit racism in law enforcement continues to endure. There is ample evidence to demonstrate that it does.

This work provides an innovative new look at police ethics, including results from an updated version of the classic Police Integrity Questionnaire, including new social and technological advances. It aims to push the study of police research further, expanding on and testing police integrity theory and methodology, the relationship between community and integrity, and the influence of multiculturalism and globalization on policing and community attitudes.

This work brings together experienced scholars who have used the police integrity theory and the accompanying methodology to measure police integrity in eleven countries, and provide advance and sophisticated explorations of the topic. Organized into three thematic sections, it explores the testing methodology for international comparisons, insights into police-community relations, and explores police subcultures.

This book critically examines coordination work between police officers and agencies. Police work requires constant interaction between police forces and units within those forces, yet the process by which police work with one another is not well understood by sociologists or practitioners. At the same time, the increasing inter-dependence between police forces raises a wide set of questions about how police should act and how they can be held accountable when locally-based police officers work in or with multiple jurisdictions. This rearrangement of resources creates important issues of governance, which this book addresses through an inductive account of policing in practice.Policing Integration builds on extensive fieldwork in a multi-jurisdictional environment in Canada alongs.

Police culture is often considered as both a cause of police deviance and an obstacle for police reform. In this study of police racism and police reform in Australia, Janet Chan provides a critical assessment of police initiative in response to the problem of policeSHminorities relations. The book examines the dynamics of change and resistance within an organization and captures the complexity and unpredictability of the change process. It questions the utility of the traditional conception of police culture and proposes a new framework for understanding the interrelationships among the structural conditions of police work, police cultural knowledge, and police practice. A highly original and valuable contribution to policing studies and studies of organizational reform, the book is both empirically rich and theoretically informed.

In this illuminating history that spans past campaigns against piracy and slavery to contemporary campaigns against drug trafficking and transnational terrorism, Peter Andreas and Ethan Nadelmann explain how and why prohibitions and policing practices increasingly extend across borders. The internationalization of crime control is too often described as simply a natural and predictable response to the growth of transnational crime in an age of globalization. Andreas and Nadelmann challenge this conventional view as at best incomplete and at worst misleading. The internationalization of policing, they demonstrate, primarily reflects ambitious efforts by generations of western powers to export their own definitions of "crime," not just for political and economic gain but also in an attempt to promote their own morals to other parts of the world.

A thought-provoking analysis of the historical expansion and recent dramatic acceleration of international crime control, Policing the Globe provides a much-needed bridge between criminal justice and international relations on a topic of crucial public importance.

Under contract with Charlotte, North Carolina, the authors evaluated three of the six policing and public-safety recommendations in the city's SAFE Charlotte: Safety and Accountability for Everyone report. Recommendation 2 is about developing ways to implement a civilian response for low-risk duties. Recommendation 3 requested independent analysis of police–community member contact to determine the extent to which racial/ethnic bias is evident in policing in Charlotte. Recommendation 4 states that Charlotte's Community Policing Crisis Response Team should be expanded, and a specialized civilian responder model should be explored for those experiencing mental health crisis and homelessness.

  The authors recommend two pilot programs: (1) a new team of clinicians who would deploy in pairs to provide services that could help address substance abuse, mental health, and homelessness and (2) a program that would delegate low-risk, low-priority calls to nonspecialized civilian responders. The estimated costs for the clinician team pilot would be approximately $850,000 for the first year. The estimated costs for the pilot of civilian responders for low-risk, low-priority calls would be approximately $1.4 million to $1.85 million for the first year. Local stakeholders should be involved in every aspect of development and implementation of all potential programs — from hiring to uniforms. The authors analyzed stop data, arrest data, and complaint data and found that Black residents in Charlotte were more likely to be stopped both as a driver and as a pedestrian and, when stopped, were more likely to be arrested.

In this report, RAND Corporation researchers summarize what is currently known about killings committed by police officers in the United States and identify existing evidence about various ways to prevent these killings. A relatively large body of research on these topics exists, but these studies often suffer from methodological shortcomings, largely stemming from the dearth of available data. Recognizing the need for more-rigorous work to guide efforts to reform police — and, more specifically, to reduce police killings — the authors present work focused on the development of a research agenda, or a road map, to reduce police killings. The report, based on an extensive literature review as well as interviews with policing experts, contains a series of recommendations for areas in which research efforts may be most effective in helping inform policy-making and decision-making aimed at reducing police killings.

The authors identified six focus areas — foundational issues (such as racial inequities, police culture, and police unions), data and reporting, training, policies, technology, and consequences for officers. Reviewing the priority research topics in each focus area, similar themes emerged, especially around the need for more-extensive and more-systematic data collection and around the use of agency policies to better govern a range of operations related to police violence, such as data collection and reporting and technology.

  In this report, the authors use the terms police killings, police violence, and police shootings to describe these types of police behaviors, whether wrongful or not. The authors identify specific instances of these behaviors as misconduct, illegality, wrongful, or excessive when those descriptions apply.

Congress enacted the Death in Custody Reporting Act of 2013 (DCRA) to address the lack of reliable information about law enforcement–related deaths and deaths in correctional institutions. The U.S. Department of Justice has conducted several activities designed to respond to the provisions specified in the DCRA legislation, as well as their own federal mandates, toward a comprehensive understanding of the prevalence and characteristics of deaths that occur in law enforcement custody. Despite these efforts, no national data collection program currently describes all deaths that occur in law enforcement custody. These data are critical to support strategies to reduce such deaths; to promote public safety through appropriate responses to reported crimes, calls for service, and police-community encounters; and to build trust with communities.

• More.....

  To better understand the needs around developing and leveraging data from a national data collection of law enforcement–related deaths, RTI International and the RAND Corporation, on behalf of the National Institute of Justice, convened a panel of experts to discuss the challenges to conducting a national data collection, to recommend potential solutions to those challenges, and to recommend research and other applications for the collected data. Through a three-session virtual workshop, participants identified 19 high-priority needs to support a comprehensive and robust data collection program on law enforcement–related deaths. These high-priority needs address challenges related to scope, definition, and detail of the collection; data collection elements and reporting needs; and the utility of the information to inform law enforcement training, programs, and policies.

Strategic Decision Support Centers (SDSCs) are the Chicago Police Department's district-level real-time crime centers, launched in January 2017 and expanded in 2018. They serve as command and control centers for staff to gain awareness of what is happening in their districts and decide on responses. SDSCs support daily and weekly planning meetings and provide near–real-time support for detecting, responding, and investigating crimes as they occur. Their objectives are to improve districts' abilities to reduce crime, hold offenders accountable, improve officer safety, and reduce service times.

In this report, the authors evaluate the processes, organizational structures, and technologies employed in the SDSCs. They also assess the extent to which the introduction of SDSCs was associated with reductions in crime levels in the districts. They find that SDSCs are a promising tool for supporting crime reduction. According to the authors' models, a district that adds an SDSC can expect to see reductions in at least some of the ten types of major crimes modeled, including shootings, robbery, burglary, and criminal sexual assault.

More broadly, the authors see SDSCs as a promising model for improving law enforcement agencies' awareness of their communities, improving their decision-making, and carrying out more effective and more efficient operations that lead to crime reductions and other policing benefits.

A guiding tenet of community policing is that trust and mutual respect between law enforcement and communities will more effectively address long-standing and complex public safety issues. One strategy to help establish such confidence is for law enforcement to adequately represent the demographic characteristics of the community it serves. Working to achieve this strategy can be challenging, however, because not everyone will be aware of, qualified for, or interested in a law enforcement career. The Colorado State Patrol (CSP) seeks to better reflect the demographic representation of the state of Colorado. This report offers an exploratory examination of how CSP's recruiting and selection policies and procedures relate to that objective. By integrating a review of CSP documents, interviews with CSP experts, and research and industry best practices, the authors identified potential barriers to diversity in CSP's early career stages and provide recommendations to mitigate and remove these barriers. This work is meant to act as a preliminary road map to assist CSP's future efforts in diversifying the demographic representation of its workforce. Barriers to diversity include the composition of the current workforce, the nature of the job, relocation requirements, and the lengthy hiring process. Recommendations include assessing propensity to apply, determining why applicants drop out, adjusting application windows, exploring strategies to shorten background investigations, and providing a realistic job preview.

The Los Angeles Police Department is completing one of the most ambitious experiments in police reform ever attempted in an American city. After a decade of policing crisis that began with the beating of Rodney King in 1991 and culminated in the Rampart police corruption scandal in 1999, the U.S. Department of Justice announced in May 2000 that it had accumulated enough evidence to sue the City of Los Angeles over a pattern-and-practice of police misconduct. Later that year, the city government entered a "consent decree" promising to adopt scores of reform measures under the supervision of the Federal Court. The experiment in police reform in Los Angeles has two components: the consent decree produced by the Justice Department’s intervention, and the leadership of Chief William Bratton, who since 2002 has focused the Department’s attention simultaneously on reducing crime, improving morale, and complying fully with the consent decree. What has the experience in Los Angeles revealed about policing under a consent decree?

• More.....

  Has the consent decree achieved its purpose? How is the Los Angeles Police Department controlling its use of force; what is the state of police-community relations; how rigorous is the governance and oversight of the LAPD; and how is the culture of the Department changing? Most important, as the LAPD has incorporated the policies and practices specified in the consent decree into its own operations and management, has the Department won the public’s trust and confidence while reducing crime and bringing offenders to justice? To answer those questions, the Program in Criminal Justice Policy and Management at the Harvard Kennedy School examined the LAPD using multiple research methods. We undertook hundreds of hours of participant observation from patrol to the command staff; we analyzed administrative data on crime, arrests, stops, civilian complaints, police personnel, and the use of force. We compiled surveys conducted over the last decade of police officers and residents of Los Angeles, and then conducted three surveys of our own, one of residents, another of LAPD officers, and a third of detainees recently arrested by the LAPD. Finally, we conducted a series of formal focus groups and structured interviews with police officers, public officials, and residents of Los Angeles. While some questions remain unanswered, this ranks among the most comprehensive assessments ever conducted of a police department outside of a time of crisis. We found the LAPD much changed from eight years ago, and even more so in the last four or five years.Description text goes here

Stark racial inequity has long been a deeply troubling aspect of our criminal justice system. In recent years, traffic stops have emerged as a key factor driving some of these inequities and an area of potential reform. Are there opportunities to identify kinds of traffic stops that could be enforced in alternative ways—potentially improving officer and civilian safety, enhancing police efficiency, and reducing racial disparities—without jeopardizing road safety?

To explore this question, in this report we use data on 3.4 million traffic stops made in 2019 by California’s 15 largest law enforcement agencies to examine racial disparities in stop outcomes and experiences across time of the day, type of law enforcement agency, and type of traffic violation.

Suspect Citizens offers the most comprehensive look to date at the most common form of police-citizen interactions, the routine traffic stop. Throughout the war on crime, police agencies have used traffic stops to search drivers suspected of carrying contraband. From the beginning, police agencies made it clear that very large numbers of police stops would have to occur before an officer might interdict a significant drug shipment. Unstated in that calculation was that many Americans would be subjected to police investigations so that a small number of high-level offenders might be found. The key element in this strategy, which kept it hidden from widespread public scrutiny, was that middle-class white Americans were largely exempt from its consequences. Tracking these police practices down to the officer level, Suspect Citizens documents the extreme rarity of drug busts and reveals sustained and troubling disparities in how racial groups are treated.

I examine how racial disparities in police use of force vary using new data covering every municipal police department in New Jersey. Along the intensive margin of force, I find disparities that disfavor Black subjects and are larger at higher force levels, even after adjusting for incident-level factors and using new techniques to limit selection bias. I then extend empirical Bayes methods to estimate department-specific racial disparities and observe significant differences across and within these hundreds of departments. Finally, I find that certain municipal factors are useful predictors of whether a department has a large racial disparity against Black civilians, but the most informative variables can change when considering different levels of force. These findings suggest that ignoring heterogeneity in police use of force misrepresents the problem and masks the existence of both departments with very large disparities and those without apparent disparities against Black civilians, but the variation even within departments may make identifying and treating inequitable departments difficult.

Biased police officers may purposely mis-record, or mask, the race of citizens that they interact with in order to evade detection. Indeed, journalists uncovered widespread evidence of such masking among Texas Highway troopers from 2010 to 2015. I propose a new test of racial bias in the presence of masking that is more powerful than standard tests and is well-suited to explore the rich heterogeneity in bias. Using various data-driven techniques to detect masking, I estimate that 24% of 130,240 searches were masked, with over half being Hispanic drivers being mis-recorded as white when searches failed to turn up contraband. I find that Hispanic and white troopers are biased against non-white motorists, with Hispanic motorists being treated the most unfairly. Using my model, I also find evidence of institutional racial bias and ‘bad apple’ troopers across Texas.

Nonrandom selection into police encounters typically complicates evaluations of law enforcement discrimination. This study overcomes selection concerns by examining automobile crash investigations, for which officer dispatch is demonstrably independent of drivers’ race. I find State Police officers issue significantly more traffic citations to drivers whose race differs from their own. This bias is evident for both moving and nonmoving violations, the latter indicating a preference for discriminatory leniency towards same-race individuals. I show this treatment is unmitigated by socioeconomic factors: officers cite other-race drivers more frequently regardless of their age, gender, vehicle value, or characteristics of the local community.

In 1981, the Commission issued a seminal report on police practices in America, Who is Guarding the Guardians? Twenty years later the Commission issued a follow-up report, Revisiting Who is Guarding the Guardians? Both reports raised troubling concerns about insular police practices that undermine equal protection under the law. Now, forty years after the Commission’s first report on police practices, a number of public incidents involving police conduct have returned such concerns to the forefront of national conversation. The Black Lives Matter movement was founded in 2013 in response to the acquittal of George Zimmerman for the death of Trayvon Martin.1 The movement has increasingly gained national attention since its founding through organizing and demonstrations against racial inequality, particularly police use of force against Black people. High profile incidents of deadly force by police include the deaths of Michael Brown in Ferguson, MO, Tamir Rice in Cleveland, OH, Walter Scott in North Charleston, SC, Sandra Bland, in Prairie View, TX, and many others. In June 2020, protests against police use of force, particularly force against Black victims, became one of the largest protest movements in U.S. history, with about 15 million to 26 million people in the United States participating in demonstrations. 2 These protests started in response to the killings of Ahmaud Arbery, George Floyd, and Breonna Taylor. The movement calls for widespread police reform and accountability for allegedly race-motivated violence against people of color, as well as calling for broader race equity in the U.S.3 On June 6, 2020 an estimated half a million people participated in public protests in nearly 550 places across the United States. As of July 3, 2020, there had been an estimated 4,700 demonstrations in all 50 states.

Examines the characteristics and experiences of persons age 16 or older who contacted police to request assistance in 2011. The report describes the perceptions of residents about police behavior and response during these encounters. It details requests for police assistance to (1) report a crime, suspicious activity, or neighborhood disturbance; (2) report a non-crime emergency, such as a medical issue or traffic accident; and (3) seek help for a nonemergency or other reason, such as asking for directions or help with an animal problem. Data are from the 2011 Police-Public Contact Survey (PPCS), a supplement to the National Crime Victimization Survey, which collects information from a nationally representative sample of persons in U.S. households on contact with police during a 12-month period.

Examines the characteristics and experiences of persons age 16 or older who were stopped by police during traffic and street stops, and their perceptions of police behavior and response during these encounters. It describes the outcomes of traffic and street stops by the reason for the stop; demographic characteristics of the persons stopped; race or Hispanic origin of the officers; and whether a ticket was issued, a search was conducted, or force was used. It also describes variations in perceptions of the police across characteristics and outcomes of traffic and street stops.

To assess racial disparities in police interactions with the public, we compiled and analyzed a dataset detailing over 60 million state patrol stops conducted in 20 U.S. states between 2011 and 2015. We find that black drivers are stopped more often than white drivers relative to their share of the driving-age population, but that Hispanic drivers are stopped less often than whites. Among stopped drivers—and after controlling for age, gender, time, and location— blacks and Hispanics are more likely to be ticketed, searched, and arrested than white drivers. These disparities may reflect differences in driving behavior, and are not necessarily the result of bias. In the case of search decisions, we explicitly test for discrimination by examining both the rate at which drivers are searched and the likelihood searches turn up contraband. We find evidence that the bar for searching black and Hispanic drivers is lower than for searching whites. Finally, we find that legalizing recreational marijuana in Washington and Colorado reduced the total number of searches and misdemeanors for all race groups, though a race gap still persists. We conclude by o↵ering recommendations for improving data collection, analysis, and reporting by law enforcement agencies.
