Less Prison, More Police, Less Crime: How Criminology Can Save the States from Bankruptcy

April 2010

Professor Lawrence Sherman explains how policing can prevent far more crimes than prison per dollar spent. His analysis of the cost-effectiveness of prison compared to policing suggests that states can cut their total budgets for justice and reduce crime by reallocating their spending on crime: less prison, more police.

Legitimacy and Community Cooperation With Law Enforcement

August 2009

Tom R. Tyler, chair of the New York University psychology department, describes research on profiling and community policing. His research found that citizens of all races show greater respect for law enforcement when they believe officers are treating them fairly. Even citizens who experienced a negative outcome getting a traffic ticket, for example showed higher levels of respect for and cooperation with law enforcement as long as they believed they were not being singled out unfairly.

Going Home (or Not): How Residential Change Might Help the Formerly Incarcerated Stay Out of Prison

October 2011

Dr. Kirk discusses how Hurricane Katrina affected those formerly incarcerated persons originally from New Orleans and their likelihood of returning to prison. Kirk also discussed potential strategies for fostering residential change among those who were incarcerated, focusing specifically on parole residency policies and the provision of public housing vouchers.

Economical Crime Control: Perspectives from Both Sides of the Ledger

December 2011

The surge in incarceration since 1980 has been fueled in part by the mistaken belief that the population can be divided neatly into "good guys" and "bad guys." In fact, crime rates are not determined by the number of at-large criminals, any more than farm production is determined by the number of farmers. Crime is a choice, a choice that is influenced by available opportunities as much as by character. This perspective, drawn from economic theory, supports a multi-faceted approach to crime control. Dr.

Don't Jump the Shark: Understanding Deterrence and Legitimacy in the Architecture of Law Enforcement

November 2010

Deterrence theory dominates the American understanding of how to regulate criminal behavior but social psychologists' research shows that people comply for reasons that have nothing to do with fear of punishment; they have to do with values, fair procedures and how people connect with one another. Professor Meares discussed the relevance of social psychologists' emerging theory to legal theory and practice and how deterrence and emerging social psychology theories intertwine.

Changing the Behavior of Drug-Involved Offenders: Supervision That Works

December 2012

A small number of those who commit crimes are heavily involved in drugs commit a large portion of the crime in this country. An evaluation of a "smart supervision" effort in Hawaii that uses swift and certain sanctioning showed that individuals committing crimes who are heavily involved in drug use can indeed change their behavior when the supervision is properly implemented.

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.

Just Wrong: The Aftermath of Wrongful Convictions

October 2017

The strength of our criminal justice system depends on its ability to convict the guilty and clear the innocent. But we know that innocent people are sometimes wrongfully convicted and the guilty remain free to victimize others. The consequences of a wrongful conviction are far-reaching for the wrongfully convicted and the survivors and victims of the original crimes. 

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.

Are CEDs Safe and Effective?

June 2010

Thousands of law enforcement agencies throughout the United States have adopted conducted energy devices (CEDs) as a safe method to subdue individuals, but are these devices really safe? What policies should agencies adopt to ensure the proper use of this technology? This NIJ Conference Panel discusses the physiological effects of electrical current in the human body caused by CEDs, as well as how this technology can reduce injuries to officers and suspects when appropriate policies and training are followed.

Cell Phones in Prison

June 2010

Criminals are using cell phones illegally in prisons and jails to conduct their business and intimidate witnesses. Although technology solutions to this problem are available, they can create new challenges, such as legal and implementation issues associated with cell phone use in correctional facilities. Panelists will discuss various aspects to consider from how prisoners use cell phones, to day-to-day and operational aspects, to legal and regulatory concerns.

Familial DNA Searching: Issues and Answers

June 2011

Familial DNA searching is the practice of creating new investigative leads in cases where DNA evidence found at the scene of a crime strongly resembles that of an existing DNA profile but is not an exact match. Panelists will explain how the technology works, provide examples of successful convictions obtained through familial searches, and discuss the various misconceptions and concerns regarding this practice.

An Examination of Justice Reinvestment and Its Impact on Two States

June 2010

Funded in part by the Bureau of Justice Assistance and the Pew Center on the States, the justice reinvestment project is a data-driven strategy aimed at policymakers to "reduce spending on corrections, increase public safety and improve conditions in the neighborhoods to which most people released from prison return." Representatives from two states where the justice reinvestment strategy is currently being implemented will discuss how it is being used to reduce the rate of incarceration and how states can reinvest in local communities.

Prosecuting Cases of Elder Abuse
