Policing

If we want to address America’s gun violence epidemic and save lives today, fair and effective policing is essential. But for too many communities, we are failing to deliver that kind of policing.

While the homicide rate has decreased nationwide since its historic high in the 1990s, many of America’s most violent neighborhoods are experiencing higher rates of gun violence than ever before. This gun violence has exacerbated the safety gap in American cities and taken a devastating toll on communities of color. If we want to address America’s gun violence epidemic and save lives today, fair and effective policing is essential. But for too many communities, we are failing to deliver that kind of policing.

The Crime Lab works directly with police agencies and experts to evaluate interventions to improve officer training, strengthen department management, narrowly focus violence reduction efforts, and rebuild police-community relationships to make policing more fair and effective.

20-35%

Our research found that when police department leadership changes, rates of violent crime and police use of force can drop at least 20-35% – proving that management matters.

22%

Police officers who completed Sit-D, a training program designed and evaluated by the Crime Lab, engaged in 22% fewer uses of force for months after the training.
