Gun Violence


Law enforcement agencies implement a variety of strategies and methods to combat crime and ensure public safety. Policing strategies extend beyond traditional models of responding to calls for service and often seek to increase crime prevention, intervention, and response effectiveness through such techniques that focus on gun violence prevention and intervention. These strategies are aimed at reducing gun-related crimes and homicides in neighborhoods and communities. 

NIJ has funded research and evaluation projects to understand and address the issues of gun violence and gun violence prevention since the late 1990s.
