Wrongful Convictions: The Latest Scientific Research & Implications for Law Enforcement

March 2013

What does science tell us about case factors that can lead to a wrongful conviction? Dr. Jon Gould of American University will discuss the findings of the first large-scale empirical study that has identified ten statistically significant factors that distinguish a wrongful conviction from a "near miss." (A "near miss" is a case in which an innocent defendant was acquitted or had charges dismissed before trial). Following Dr. Gould's presentation, Mr. John R.

Slow Down, Move Over — Public Service Announcement

December 2012

More law enforcement officers die each year in traffic incidents than from any other cause, including shootings. Many of these deaths occur on the roadside as officers perform their duties. This public service announcement reminds drives to slow down and move over when they see a public safety responder on the side of the road. This video was produced by Respondersafety.com with funding from the National Institute of Justice, U.S. Department of Justice, and United States Fire Administration, Department of Homeland Security.

The Neurobiology of Sexual Assault: Implications for Law Enforcement, Prosecution, and Victim Advocacy

December 2012

Dr. Campbell brings together research on the neurobiology of trauma and the criminal justice response to sexual assault. She explains the underlying neurobiology of traumatic events, its emotional and physical manifestation, and how these processes can impact the investigation and prosecution of sexual assaults. Real-world, practical implications are examined for first responders, such as law enforcement, nurses, prosecutors, and advocates.

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.

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.

Game Change: How Researcher-Practitioner Partnerships Are Redefining How We Study Crime

June 2012

Opening Plenary Panel
When researchers and practitioners work side by side, they can maximize their problem-solving abilities. The research partner can focus on the data and the science; the practitioner can focus on interpreting the findings and applying them in the field. In the plenary panel, panelists described the benefits, challenges and pitfalls of researcher-practitioner partnerships with a focus on the financial benefits to the practitioner.

Looking Back to See the Future of Prison Downsizing in America

June 2012

NIJ Conference Keynote Address

The recent declines in U.S. prison populations have caused many reformers to suggest that America's experiment with mass incarceration is ending. But current prison downsizing policies may well backfire if we fail to heed the lessons learned from the intermediate sanctions movement of the 1990s. In the event attendees rated highest, Dr. Petersilia summarizes these lessons and discussed why we must consider them if we want to reverse — for good — four decades of prison expansion.

Protecting our Protectors: Using Science to Improve Officer Safety and Wellness

June 2012

Each year, 100-200 law enforcement officers die in the line of duty. Last year, 177 lost their lives — a 16-percent increase from 2010. As Attorney General Eric Holder noted, this is a devastating and unacceptable trend. NIJ has developed a robust research portfolio to improve officer safety and wellness and, ultimately, save lives. This panel discussed some of NIJ's most promising work to reduce shooting and traffic-related fatalities — consistently the leading causes of officer line-of-duty deaths — and improve officer wellness, which is inextricably linked with officer safety.

Effects of Wrongful Conviction Cases

June 2012

NIJ has funded a study examining the impact of wrongful convictions on crime victims. The study is looking at the impact on the original victim of the crime to get a better understanding of what their service needs are, and how we can better serve them both in terms of policy and practice.
