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.

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.

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.

This report addresses the impact on Miami-Dade County of the Secure Communities program, currently one of the primary federal immigration enforcement programs administered by the Department of Homeland Security (DHS) through Immigration and Customs Enforcement (ICE). DHS claims that the program prioritizes the removal of convicted criminal aliens who pose a danger to national security or public safety, repeat violators who game the immigration system, those who fail to appear at immigration hearings, and fugitives who have already been ordered removed by an immigration judge.” Contrary to these policy goals, we found that 61% of individuals ordered for removal from Miami-Dade County are either low level offenders or not guilty of the crime for which they were arrested. By ICE’s standards only 18% of the individuals ordered for removal represent high priority public safety risks, and that number drops to a mere 6% when we apply local standards suggested by Miami-Dade County’s Public Defender. Interviews with detainees also reveal that often residents are stopped by police for no apparent reason and subjected to detention and deportation. Secure Communities in Miami-Dade County also has a disproportionately negative impact on Mexicans and Central Americans who constitute a relatively low percentage of the local population but a high percentage of those whom Secure Communities detained and removed.

Executive Summary This report presents findings from a survey of Latinos regarding their perceptions of law enforcement authorities in light of the greater involvement of police in immigration enforcement. Lake Research Partners designed and administered a randomized telephone survey of 2,004 Latinos living in the counties of Cook (Chicago), Harris (Houston), Los Angeles, and Maricopa (Phoenix). The survey was designed to assess the impact of police involvement in immigration enforcement on Latinos’ perceptions of public safety and their willingness to contact the police when crimes have been committed. The survey was conducted in English and Spanish by professional interviewers during the period November 17 to December 10, 2012. Survey results indicate that the increased involvement of police in immigration enforcement has significantly heightened the fears many Latinos have of the police, contributing to their social isolation and exacerbating their mistrust of law enforcement authorities.

With the close proximity of gangs and the easy access to drugs, keeping urban neighborhoods safe from crime has long been a central concern for residents. In <em>Clean Streets, Patrick Carr draws on five years of research in a white, working-class community on Chicago’s South side to see how they tried to keep their streets safe. Carr details the singular event for this community and the resulting rise of community activism: the shootings of two local teenage girls outside of an elementary school by area gang members. As in many communities struck by similar violence, the shootings led to profound changes in the community's relationship to crime prevention. Notably, their civic activism has proved successful and, years after the shooting, community involvement remains strong.

Carr mines this story of an awakened neighborhood for unique insights, contributing a new perspective to the national debate on community policing, civic activism, and the nature of social control. <em>Clean Streets offers an important story of one community's struggle to confront crime and to keep their homes safe. Their actions can be seen as a model for how other communities can face up to similarly difficult problems.

The ideologies that foment extremist violence are varied and grounded in online communities and social networks. Today, individuals from any community, any walk of life, from any part of the world, can become inspired, indoctrinated and mobilized to conduct violence in the name of a cause. These globalized problems have local impacts and gaining a better understanding of those impacts is the first essential step in pursuing prevention. It is exactly this idea that underpins this report. Canada and Alberta are peaceful and prosperous - home to a liberal, democratic and multicultural society. The impacts and manifestations of extremism outlined in this report are surprising to many of us and are further evidence of the growing diffusion of extremism globally. These impacts are not unique to Alberta; there are no characteristics that make the province more susceptible to extremism,

Drawing on more than a year of research and hundreds of interviews with community leaders, human service professionals, victims and perpetrators, and members of law enforcement, this report provides a holistic and highly localized understanding of the problem and represents both a historical overview and a snapshot of extremism in Alberta during 2018.

Tthe current use of electro-shock weapons as well as the governing regulations in The Netherlands raise serious concerns and therefore Amnesty International calls the Dutch police to: – suspend the use of electro-shock weapons by all police units currently using them until a suitable legal and operational framework for their use has been set up that is in line with the obligations of The Netherlands under international human rights law and standards and – until this is done – to withdraw all electro-shock weapons distributed; – refrain from widespread distribution of electro-shock weapons in day-to-day policing; – cease any police interventions in mental health institutions in all situations and circumstances that do not amount to immediate life threatening emergencies (e.g. hostage situations). … This briefing sets out the background to the current pilot project conducted by the Dutch police on the general deployment of electro-shock weapons in day-to-day policing (I.). It further provides a summary of the Amnesty International’s main findings regarding the human rights concerns of the first pilot phase as well as the overall set up of the project and its interim evaluation (II.). These findings are then more in detail explained and elaborated in section III., followed by a conclusion and some recommendations (IV.).

According to the FBI, there were over 1.5 million burglaries in the U.S. in 2016, with almost 70% residential (FBI, 2017a). Combined, the victims of burglary suffered over $3.6 billion in lost property (about $2,400/burglary). Yet, only about 13% of burglaries reported to the police were cleared (FBI, 2017b). While more prevalent than violent crime, burglary rarely generates attention and headlines. Yet, the sense of violation and vulnerability typical of residential burglary victims is considerable, and so prevention would seem the best solution. The Near Repeat Phenomenon The biggest challenge facing crime prevention in policing is the need to correctly anticipate where and when crime will occur (Pease & Laycock, 1999). Hot spots policing focuses on the locations where crimes occur frequently, though knowing when they will occur can help law enforcement effectively deploy personnel. Repeat victimization occurs when the same target is victimized again. However, the “Near Repeat” (NR) phenomenon (Morgan, 2001) is when those that live near to a burglary victim are victimized soon after; in other words, when one home is burglarized, for a particular time period afterwards, homes nearby are at an elevated risk of burglary. Empirical research has clearly confirmed the existence of NR burglary patterns. The exact spatial and temporal extent of increased risk varies; however, we know the increased risk level that occurs after a burglary is temporary, suggesting police must act quickly to maximize the potential for reaping crime prevention benefits.

The objective of this project was to test the efficacy of swift resident notification for preventing subsequent burglaries within near-repeat high-risk zones (NR-HRZ). The experiment was conducted in Baltimore County, Maryland and Redlands, California. As residential burglaries came to the attention of the police, a trickle randomization process was used to assign each micro-level NR-HRZ (measured 800 ft, 244 m from the burglary location) and associated buffer (400 ft, 122 m) to treatment or control. Treatment was performed by uniform agency volunteers and consisted of swift notification to residents in the area of increased risk of burglary victimization. Treatment and control zones were compared for differences in the mean count of residential burglary using independent samples t tests. Two surveys were administered to gauge the impact of the program: one targeted residents and one targeted at the treatment providers. There was limited evidence that the treatment reduced follow-on burglaries. The effectiveness of the intervention varied depending on the post-intervention time period being considered. The results of the community survey suggested that: (1) the most frequent crime prevention actions taken by residents were relatively low-cost and low-effort and (2) notification did not increase resident fear of burglary. The treatment provider survey found that the program was effective at increasing the level of engagement between volunteers and the agency and had positive impacts on community perception. This research demonstrated that law enforcement volunteers can be used to undertake programs that have positive impacts on police-community relations. Limitations included low near-repeat counts, delays in discovering/reporting burglary, and staffing constraints.

This literature review summarises the findings of international studies of what works in police practice to reduce residential burglary, drawing largely on the outcomes of research in the UK, the US and Australia. Residential burglary is one of the most common crimes, of great concern to the general public as reflected in crime victim surveys, and regarded as a major problem by police forces studied in the literature. Internationally there has been an increasing adoption of proactive policing with considerable research effort aimed at evaluating the effectiveness of crime prevention approaches. As part of this evaluative effort, the question ‘what works?’ has been applied to initiatives to reduce residential burglary.

Residential burglary is generally regarded as a particularly serious crime both because of the financial and material losses to victims and because of the psychological upset which may follow a break-in (Maguire, 1982). It is also a fairly common crime and accounts for a substantial part of the load on the police, the courts and the prison system. In 1980, about 295,000 burglaries to residential property were recorded by the police in England and Wales and these accounted for some 11% of what in official statistics are now called 'serious offences recorded by the police' (Criminal Statistics, 1980). Only 29% of these residential burglaries were 'cleared up' compared with a clear-up rate of 41 % for all serious offences. Yet, in 1980, burglars receiving prison sentences for offences against residential and non-residential properties still accounted for nearly half of all receptions into prison of males under 21 and nearly a quarter of those over 21 (Prison Statistics, 1980). On the basis of offences recorded by the police in 1980 and the numbers of households recorded in the 1971 census, a rough estimate of the average risk of burglary to households in England and Wales was 1 in 55. Risk figures however are higher when account is taken of offences not reported to the police. According to recent evidence from the General Household Survey (see Criminal Statistics, 1980) these represent some 40% of all residential burglaries which occur. On the basis of both reported and unreported crimes, then, the average risk of burglary to households in 1980 may have been closer to 1 in 35 than 1 in 55.

Extortion has become an endemic problem in Central America. To provide a comprehensive response to this crime, the countries of the region have begun to make use of asset forfeiture, a tool that reduces the financial assets available to organized crime.

This paper describes how this legal procedure has evolved and been applied in the region, sets out the advantages it offers in the fight against organized crime and proposes strategies for better implementation.
