The study contains data from a survey of 480 large (200+ sworn officers) state and local law enforcement agencies, and 63 additional smaller county and municipal agencies that experienced violent extremism. These data were collected as part of a project to perform a comprehensive assessment of challenges and opportunities when developing partnerships between police and communities to counter violent extremism. Qualitative data collected as a part of this project are not included in this release.

This collection includes one tab-delimited data file: "file6-NIJ-2012-3163-Survey-Responses.csv" with 194 variables and 382 cases.

The Drug Market Intervention (DMI) has been identified as a promising practice for disrupting overt-drug markets, reducing the crime and disorder associated with drug sales, and improving police-community relations. Montgomery County, Maryland; Flint, Michigan; Guntersville, Alabama; Lake County, Indiana; Jacksonville, Florida; New Orleans, Louisiana; and Roanoke, Virginia applied for and received DMI training and technical assistance from Michigan State University in 2010 and 2011. This study followed the seven sites that were trained in the program to determine how the program was implemented, how the DMI affected the targeted drug market, whether the program affected crime and disorder, whether the program improved police-community relations, and how much the program cost.

This study was a multi-site evaluation of a presumptive drug detection technology (PDDT) developed by Mistral Security Incorporated (MSI). The evaluation was conducted by Justice and Security Strategies, Inc. (JSS) in work release programs, probation and parole offices, and drug courts in three states: Alabama, Florida, and Wyoming. Also, interviews with the offenders, corrections staff, and program administrators were conducted.

This study evaluated CeaseFire, a program of the Chicago Project for Violence Prevention. The evaluation had both outcome and process components.

The outcome evaluation assessed the program's impact on shootings and killings in selected CeaseFire sites. Two types of crime data were compiled by the research team: Time Series Data (Dataset 1) and Shooting Incident Data (Dataset 2). Dataset 1 is comprised of aggregate month/year data on all shooting, gun murder, and persons shot incidents reported to Chicago police for CeaseFire's target beats and matched sets of comparison beats between January 1991 and December 2006, resulting in 1,332 observations. Dataset 2 consists of data on 4,828 shootings that were reported in CeaseFire's targeted police beats and in a matched set of comparison beats for two-year periods before and after the implementation of the program (February 1998 to April 2006).

The process evaluation involved assessing the program's operations and effectiveness. Researchers surveyed three groups of CeaseFire program stakeholders: employees, representatives of collaborating organizations, and clients.

The three sets of employee survey data examine such topics as their level of involvement with clients and CeaseFire activities, their assessments of their clients' problems, and their satisfaction with training and management practices. A total of 154 employees were surveyed: 23 outreach supervisors (Dataset 3), 78 outreach workers (Dataset 4), and 53 violence interrupters (Dataset 5).

The six sets of collaborating organization representatives data examine such topics as their level of familiarity and contact with the CeaseFire program, their opinions of CeaseFire clients, and their assessments of the costs and benefits of being involved with CeaseFire. A total of 230 representatives were surveyed: 20 business representatives (Dataset 6), 45 clergy representatives (Dataset 7), 26 community representatives (Dataset 8), 35 police representatives (Dataset 9), 36 school representatives (Dataset 10), and 68 service organization representatives (Dataset 11).

The Client Survey Data (Dataset 12) examine such topics as clients' involvement in the CeaseFire program, their satisfaction with aspects of life, and their opinions regarding the role of guns in neighborhood life. A total of 297 clients were interviewed.

This project aimed to develop new insights into offender decision-making in hot spots in New York City, and to test whether these insights could inform interventions to reduce crime in hot spots. There were two phases to the project. In the first phase a set of hypotheses were developed about offender decision-making based on semi-structured interviews with individuals who were currently incarcerated, formerly incarcerated individuals, individuals currently on probation, and community members of high crime areas with no justice-involvement. These interviews suggested several factors worthy of further testing. For instance, offenders believed they were less likely to get away with a crime if they knew more about the officers in their community. That is, when police officers were less anonymous, offenders were less likely to go forward with a crime.

In the second phase a field intervention was developed and conducted to test whether reducing officer anonymity might deter crime. Through a randomized controlled trial (RCT) while working with NYPD neighborhood coordination officers, who work in New York City Housing Authority (NYCHA) developments, it was tested whether sending information about officers to residents in housing developments would deter crime in those developments.

The study gathered information from police officers and residents of four different community areas that had undergone some form of police consolidation or contracting. The communities were the city of Pontiac in Michigan; the cities of Chisago and Lindstrom in Minnesota; York and Windsor Townships and the boroughs of Felton, Jacobus, Yoe, Red Lion, and Windsor in Pennsylvania; and the city of Compton in California. Surveys were administered to gauge the implementation and effectiveness of three models of police consolidation: merger of agencies, regionalization under which two or more agencies join to provide services in a broader area, and contracting by municipalities with other organizations for police services.

The National Initiative for Building Community Trust and Justice (the National Initiative) is a joint project of the National Network for Safe Communities, the Center for Policing Equity, the Justice Collaboratory at Yale Law School, and the Urban Institute, designed to improve relationships and increase trust between communities and law enforcement.

Funded by the Department of Justice, this mixed-methods evaluation aimed to assess outcomes and impacts in six cities that participated in the National Initiative, which include Birmingham, AL; Fort Worth, TX; Gary, IN; Minneapolis, MN; Pittsburgh, PA; and Stockton, CA. The data described herein represent two waves of surveys of residents living in the highest-crime, lowest-income residential street segments in the six National Initiative cities.

The first wave was conducted between September 2015 and January 2016, and the second wave was conducted between July and October 2017. Survey items were designed to measure neighborhood residents' perceptions of their neighborhood conditions--with particular emphases on neighborhood safety, disorder, and victimization--and perceptions of the police as it relates to procedural justice, police legitimacy, officer trust, community-focused policing, police bias, willingness to partner with the police on solving crime, and the law.

The data described herein are from pre- and post-training assessment surveys of officers who participated in three trainings: 1) procedural justice (PJ) conceptual training, which is the application of PJ in the context of law enforcement-civilian interactions, as well as its role in mitigating historical tensions between law enforcement and communities of color; 2) procedural justice tactical, which provided simulation and scenario-based exercises and techniques to operationalize PJ principles in officers' daily activities; and 3) implicit bias, which engaged officers in critical thought about racial bias, and prepared them to better identify and handle identity traps that enable implicit biases. Surveys for the procedural justice conceptual training were fielded between December 2015 and July 2016; procedural justice tactical between February 2016 and June 2017; and implicit bias between September 2016 and April 2018. Survey items were designed to measure officers' understanding of procedural justice and implicit bias concepts, as well as officers' levels of satisfaction with the trainings.

Recognizing that violence can be an intractable problem in many communities and that there are numerous approaches to both an immediate violence problem and the range of root causes behind violence, the National Institute of Justice funded an investigation into what factors underlie violence and efforts being implemented to address those factors and potentially reduce violence at the community level. In this mixed methods study, the RAND Corporation drew on data from key informant interviews, community surveys, administrative data, and geographic data to examine specific factors that contribute to violence, as well as a range of anti-violence efforts that have been used to address violence levels in two U.S. communities: the Bullseye area of Durham, North Carolina, and the Northside (North Minneapolis) neighborhood of Minneapolis, Minnesota. Specifically, the research project aimed to answer the following questions:

1. What are community level factors that can contribute to persistent violence?
2. What are the key factors in both cities that distinguish high violent crime areas compared to low violent crime areas?

This collection contains final analytic datasets for Durham (DS1) and Minneapolis (DS2), violent crime rate data (DS3), community survey data for Durham (DS4) and Minneapolis (DS5), and multiple datasets containing community-level contextual factors from the American Community Survey (ACS) and geographical data from the U.S. Census Bureau (2009-2018) that were used to build the final analytic datasets (DS6-DS11). Qualitative data from key informant interviews and GIS data are not available for download at this time. Access to Durham and Minneapolis community survey data is restricted.

This study interviewed young men living in New York City about their experiences being stopped by the police on the street or in their cars. It examined how experience with the police as well as general evaluations of police policies, practices and behaviors in the respondent's neighborhood shaped views about police legitimacy, and law related behavior, such as compliance with the law and cooperation with legal authorities.

Somalis in North America offer a window into the remarkable potential that can be realized by refugees/immigrants despite experiences of severe adversity as well as the challenges some subgroups encounter when adjusting to life in a new country. Somalia has endured one of the longest and most brutal wars of the past 30 years. This enduring conflict has led to millions of Somalis being dispersed as refugees across the globe. As refugees with limited resources, many Somalis in North America are resettled in poor urban neighborhoods where they are visibly different, not only because of race or ethnicity but also because of dress, especially for women who wear a Muslim head covering.

In addition, the community has been plagued by violence. While the number of Somali American youth joining these groups are small and while the majority of Somali Americans are law-abiding citizens, the terrorist groups' ability to recruit these youth and to convince some of them to engage in violent acts is concerning, not only to policymakers and law enforcement, but also to the Somali community, which fears losing more youth to violence or having the community's reputation sullied by being associated with terrorism.

While some of the social and cultural factors affecting Somalis are unique to that ethnic group, they also share experiences common to many immigrants, navigating identity development and duality as they move between home and host cultures, contending with discrimination as religious, racial and ethnic minorities, and striving to achieve their dreams while struggling to gain socioeconomic stability. Thus, understanding their developmental trajectories may inform the understanding of other immigrant and refugee groups as well.

No valid and reliable measurement for risk for violent extremism exists; there is no single profile or set of risk factors that can accurately determine who is most at risk for engaging in violent extremist acts. The study did not attempt to determine who is most at risk. Rather, the researchers sought to identify broad attitudes that would indicate a general openness to, or rejection of, the use of violence or illegal actions in support of a political cause.

The qualitative interviews feature experiences of formal (e.g. police) and informal (e.g. community) institutions over the past year. Examples of interview prompts include questions related to social bonds with family and community, and interactions with police.
