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.

Crime Mapping and Hot Spots Policing

October 2009

David Weisburd, recipient of the 2010 Stockholm Prize in Criminology, explains research showing that intensified police patrols in high-crime hot spots can substantially decrease crime without causing it to rise in other areas. He explains the effectiveness of policing that concentrates prevention efforts at less than 5 percent of all street corners and addresses where more than 50 percent of urban crime occurs. The evidence suggests that crimes depend not just on criminals, but also on policing in key places.
