For this study, researchers conducted an experimental evaluation of a training program aimed at promoting the use of procedural justice by officers in the Seattle Police Department (SPD). After identifying eligible officers using a specially designed High Risk Circumstance (HRC) model, researchers arranged non-disciplinary supervisory meetings for participants in which procedural justice behaviors were modeled. Participating officers were then asked to fill out comment cards about the experience. Using the control and engagement groups, researchers evaluated the impact that procedural justice training had on a number of outcomes including arrests, warnings and citations, use of force, and citizen complaints. In addition to participant comment cards, researchers assessed outcomes by analyzing the administrative data collected by the Seattle Police Department.

The files have been zipped by NACJD for release, but not checked or processed except of the removal of direct identifiers. Users should refer to the accompany readme file for a brief description of the files available with this collections and consult the investigator(s) if further information is needed.The purpose of the study was to implement a "platform-based" methodology for collecting data about police organizations and the communities they serve with the goals of generating in-depth standardized information about police organizations, personnel and practices and to help move policing in the direction of evidence-based "learning-organizations" by providing judicious feedback to police agencies and policy makers. The research team conducted three web-based Law Enforcement Organizations (LEO) surveys of sworn and civilian law enforcement employees (LEO Survey A Data, n=22,765; LEO Survey B Data, n=15,825; and LEO Survey C Data, n=16,483). The sample was drawn from the 2007 Law Enforcement Management and Administrative Statistics (LEMAS) database. Agencies with 100 to 3,000 sworn police personnel were eligible for participation. To collect data for the Police-Community Interaction (PCI) survey (PCI Data, n=16,659), each week department employees extracted names and addresses of persons who had recent contact with a police officer because of a reported crime incident, traffic accident or traffic stop. Typically, the surveys were completed within two to four weeks of the encounter.

Users should refer to the accompany readme file for a brief description of the files available with this collections and consult the investigator(s) if further information is needed.The National Police Research Platform was designed to a) strengthen the science of policing by generating timely, in-depth, longitudinal information about policing organizations, personnel and practices and, b) move policing in the direction of evidence-based "learning organizations" by providing translational feedback to police agencies and policy makers. Phase I focused on testing methods and measures in 29 agencies in order to build the Platform infrastructure. First, a "total department" online methodology was successfully implemented covering numerous dimensions of organizational behavior, from supervision and accountability to employee integrity and burnout. Second, a public satisfaction contact survey was implemented in several jurisdictions to provide local external indicators of the quality of police-citizen encounters and organizational legitimacy in the community. Third, two longitudinal studies were initiated - one of new police recruits and one of new first-line supervisors - to chart their career development and identify factors that influence life trajectories. Finally, a randomized control trial was introduced in once site to test the effects of procedural justice training as part of the Platform's measurement system.

This study examined how police managers would use information about their officers' performance in procedural justice terms. The project provided for the injection of citizen assessment of service quality into systems of police performance measurement and accountability. Information on the quality of police-citizen encounters was drawn from surveys of citizens who had contact with the police in each of two cities, Schenectady and Syracuse, New York. Following the accumulation of survey data to form a baseline, survey results on citizens' satisfaction and judgments about procedural justice in their police contacts were summarized and reported to command staffs on a monthly basis through the departments' respective Compstat meetings. In this way the project provided for measures of police performance with respect to procedural justice with sufficient periodicity that the information was potentially useful in managing performance. The study addressed four specific questions: Does performance on these outcomes - procedural justice and citizen satisfaction - improve when information on these outcomes is incorporated into departments' systems of performance measurement and accountability?What do police managers do with this information, and how (if at all) are field supervisors and patrol officers affected by it?Are survey-based measures of citizens' subjective experiences valid measures of police performance, that is, do they reflect the procedural justice with which police act?Can survey based measures be deployed economically (e.g., through targeted sampling), and can other, less expensive measures of the quality of police-citizen encounters be substituted for survey-based measures? To answer these questions, researches used a mixed methods data collection plan. In both Schenectady and Syracuse, a survey was administered to people who had recent contact with the police. Semi-monthly samples were randomly drawn from police records of calls for service, stops, and arrests from mid-July, 2011, through mid-January, 2013. Across the 18 months of surveying, 3,603 interviews were completed. Also carried out, was a survey of key informants in each city - neighborhood association leaders - in order to extend the assessment of public perceptions of the local police beyond those who have direct contact with police to the larger community. Interviews with patrol officers and supervisors were also conducted in both sites, once at about the mid-point of the 18-month police services survey and again at the conclusion of the surveying. Interviews were conducted with the commanders shortly after the project was introduced to them in October of 2011. Finally, in Schenectady, "armchair" observation of a subset of the 1,800 encounters about which the citizen had already been interviewed was conducted.

This study used a mixed method approach to examine the relationship between law enforcement in the United States and researchers. A nationally-representative sample of law enforcement agencies were randomly selected and given a survey in order to capture the prevalence of police practitioner-researcher partnerships and associated information. Then, representatives from 89 separate partnerships were interviewed, which were identified through the national survey. The primary purpose of these interviews was to gain insight into the barriers and facilitators of police and practitioner relationships as well as the benefits of this partnering. Lastly four case studies were conducted on model partnerships that were identified during interviews with practitioners and researchers.

Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed. This collection was part of a larger two-phase project funded by the National Institute of Justice (NIJ). Phase I focused on the development and estimation of predictive crime models in Shreveport, Louisiana and Chicago, Illinois. Phase II involved the implementation of a prevention model using the predictive model. To evaluate the two predictive policing pilot programs funded by NIJ, RAND evaluated the predictive and preventative models employed by the Shreveport Police Department titled Predictive Intelligence Led Operational Targeting (PILOT). RAND evaluated whether PILOT was associated with a measurable reduction in crime. The data were used to determine whether or not there was a statistically significant reduction in property crime counts in treated districts versus control districts in Shreveport. The collection includes 1 Excel file (Shreveport_Predictve_Policing_Evaluation_Experiment_Data.xlsx (n=91; 8 variables)) related only to the property crime aspect of the study. Neither data used to perform the outcomes evaluation for the Chicago Police Department experiment nor qualitative data used to help perform the prediction and prevention model evaluations are available.

The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed. This study examined the impact that a six-month broken windows style policing crackdown on disorder had on residents of three California cities: Colton, Ontario and Redlands. The study investigated four questions: What is the impact of broken windows policing on fear of crime among residents of the targeted hot spots? What is the impact of broken windows policing on police legitimacy in the targeted hot spots? What is the impact of broken windows policing on reports of collective efficacy in the targeted hot spots? Is broken windows policing at hot spots effective in reducing both actual and perceived levels of disorder and crime in the targeted hot spots? To answer these questions, a block randomized experimental design was employed to deliver a police intervention targeting disorder to 55 treatment street segments with an equal number of segments serving as controls. Data were collected on the type and amount of crime before, during, and after implementation as well as interviews of residents before and after the crackdown in order to gauge their perception of its success.
