Reforming New Orleans' Criminal Justice System: The Role of Data and Research

September 2012

With its criminal justice system in disarray following Hurricane Katrina, New Orleans invited the Vera Institute of Justice to examine the city's court and jail operations. For five years, Vera has been tracking arrest-to-first-appearance time, custodial arrests versus summonses, the granting of pretrial release, and many other decision-making points. Based on analysis of these data, Vera is making policy recommendations to assist with the implementation of new procedures and to ensure performance monitoring.

The survey's findings included startling figures: More than 60 percent of the children interv​iewed were exposed to violence, crime and abuse within the past year, and more than 1 in 10 were injured in an assault.

The Evaluation of NIJ by the National Research Council of the National Academy of Sciences: NIJ's Response

June 2011

The National Academies conducted a comprehensive evaluation of the National Institute of Justice. This panel provides an overview of the evaluation and NIJ's response to it. NIJ has accepted many of the recommendations in the NRC report, and you will learn what the agency is doing to implement them.

The National Broadband (Communications) Plan: Issues for Public Safety

June 2011

The Federal Communications Commission delivered the National Broadband Plan in March 2010. As part of the plan, the FCC proposed a strategy for implementing a national public safety broadband network that would allow public safety responders anywhere in the nation to send and receive critical voice, video and data to save lives, reduce injuries, and prevent acts of crime and terror. How this strategy is implemented will have a significant impact on criminal justice and other public safety agencies nationwide, both with respect to operational capability and to resources.

Sexual Assault: Obtaining DNA From Evidence Collected up to a Week Later
