Courts, Policing and the Law

Collecting DNA from Juveniles examines the laws, policies, and practices related to juvenile DNA collection in the United States. States have increasingly required juveniles - mostly those adjudicated delinquent but also some arrestees - to submit DNA samples for analysis and inclusion in the Combined DNA Index System (CODIS), the FBI-operated national database. The report describes the issues encountered during the implementation of these laws, including the coordination challenges between the state crime labs and juvenile justice agencies, and discusses the challenges that researchers and practitioners face in assessing the effects of juvenile DNA collection on public safety outcomes.

A growing number of cities are using surveillance cameras to reduce crime, but little research exists to determine whether they’re worth the cost. With jurisdictions across the country tightening their belts, public safety resources are scarce—and policymakers need to know which potential investments are likely to bear fruit. This research brief summarizes the Urban Institute's series documenting three cities use of public surveillance cameras and how they impacted crime in their neighborhoods.

This publication is designed to guide city administrators, law enforcement agencies, and their municipal partners in implementing and employing public surveillance systems in a manner that will have the greatest impact on public safety. It details the various aspects of a system that are integral in yielding a cost-beneficial impact on crime, including budgetary considerations, camera types and locations, how best to monitor cameras, and the role that video footage plays in investigations and prosecutions. It also highlights the most prominent lessons learned in an effort to guide city administrators and jurisdictions that are currently investing in cameras for public safety purposes, as well as to inform those that are contemplating doing so.

This report summarizes the results of an evaluation of public surveillance systems in Baltimore, Chicago, and Washington, D.C., examining how systems in each of these jurisdictions were selected and implemented and assessing the degree to which they achieved their intended crime prevention impact. The study also explored whether surveillance cameras displaced crime or yielded a diffusion of benefits to areas just beyond the cameras reach, and included a cost-benefit analysis component in two of the three study sites. Findings indicate that in places where cameras were sufficiently concentrated and routinely monitored by trained staff, the impact on crime was significant and cost-beneficial, with no evidence of crime displacement.

The most extensive study of drug courts-a five-year examination of 23 courts and six comparison jurisdictions in eight states—found that these court programs can significantly decrease drug use and criminal behavior, with positive outcomes ramping upward as participants sensed their judge treated them more fairly, showed greater respect and interest in them, and gave them more chances to talk during courtroom proceedings.

Intended for all levels of law enforcement and community supervision personnel, Promoting Partnerships between Police and Community Supervision Agencies describes how these organizations build partnerships to enhance public safety. The first section of this guidebook discusses the various contributions and benefits each agency can bring to a partnership; the second discusses the key elements of partnership; and the third identifies challenges both agencies might encounter. Provided throughout the guidebook, examples of partnerships in the field offer tangible illustrations of how police and community supervision collaboration can be structured.

Volume 1 from the National Institute of Justice's Multi–site Adult Drug Court Evaluation provides information about the study’s context and objectives; a review of the literature; a description of the research design, data collection, and analytic strategies; and a description of the characteristics of study participants. The outcome evaluation included 1,781 offenders across 23 drug court and six comparison sites which represented several alternative ways the criminal justice system works with drug–involved offenders in jurisdictions without drug courts. Volume 1 also provides lessons learned in recruiting and retaining drug– and criminal justice involved–offenders in longitudinal survey research.

Volume 2 from the National Institute of Justice's Multi–site Adult Drug Court Evaluation provides information from 380 adult drug courts surveyed in 2004. It describes drug court program characteristics and operations, such as: most courts operate small programs with less than 50 participants; more than half of courts require both an eligible charge and a clinical assessment for participants to enroll; and courts that have been in operation for a longer time more often use a diversion model, whereby clients enroll in the program before entering pleas, than do younger courts. Drug courts were also classified into profiles of programming characteristics.
