Benefit-Cost Analysis for Crime Policy

February 2011

How do we decide how to allocate criminal justice resources in a way that minimizes the social harms from both crime and policy efforts to control crime? How, for that matter, do we decide how much to spend on the criminal justice system and crime control generally, versus other pressing needs? These questions are at the heart of benefit-cost analysis.

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 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.

Director’s Corner: Advancing Evidence-Based Policing

This year NIJ celebrates its fiftieth anniversary. This anniversary has been an opportunity to reflect on how far we’ve come. Fifty years ago, 911, hot spot policing, and license plate reader technology didn’t exist. We should be proud of how far we’ve come.

The concept of evidence-based practice has been on the rise over the past decade, but there is still a dramatic need for...

Addiction, the Brain, and Evidence-Based Treatment

March 2012

The criminal justice system encounters and supervises a large number of drug abusing persons. Punishment alone is a futile and ineffective response to the problem of drug abuse. Addiction is a chronic brain disease with a strong genetic component that in most instances requires treatment. Involvement in the criminal justice system provides a unique opportunity to treat drug abuse disorders and related health conditions, thereby improving public health and safety.
