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."

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

How Collaboration Between Researchers and Police Chiefs Can Improve the Quality of Sexual Assault Investigations: A Look at Los Angeles

June 2011

Panelists discuss the application of research findings from an NIJ-sponsored study of sexual assault attrition to police practice in Los Angeles. There are three main focal points: (1) the mutual benefits of researcher/practitioner partnerships, (2) the implications of variation in police interpretation of UCR guidelines specific to clearing sexual assault (with an emphasis on cases involving nonstrangers), and (3) the content of specialized training that must be required for patrol officers and detectives who respond to and investigate sex crimes.

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

June 2009

Technological advances have made it possible to detect male DNA in evidentiary samples collected several days after a sexual act has taken place. Panelists will present the research that has led to these findings, followed by a discussion of the potential impact of this work from the perspectives of the sexual assault nurse examiner (SANE) and the crime laboratory communities.

Director’s Corner: Pushing the Edge on Evidence-Based Policing - Reflections on Research for the Real World

“Most of what we do has never been tested,” pointed out Dr. Angela Hawken, before going on to explain how her organization, BetaGov, is working to change that through hundreds of rapid-implementation randomized controlled trials (RCTs). BetaGov is an innovation hub out of New York University that supports public sector practitioners conducting evaluations of their programs. Dr. Hawken has a deep research background and is...

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.

Homicide in the United States

Backlogs and Their Impact on the Criminal Justice System

June 2010

Evidence backlogs have been known to be an issue in crime laboratories. A recent study published by NIJ has shown that backlogs of untested evidence are also an issue in law enforcement evidence storage. This panel will discuss the issues and present preliminary findings from a study of the Los Angeles Police Department's and Los Angeles County Sheriff's Department's experience with clearing out a large backlog of unanalyzed rape kits.
