Project Safe Neighborhoods (PSN) is the Department of Justice's nationwide initiative that brings federal, state, local, and tribal law enforcement, prosecutors, and other public safety partners together to coordinate efforts to combat violent crime and make communities safe. Coordinated by U.S. Attorneys' offices in each of the 94 federal districts, PSN is tailored to particular communities to strategically address specific violent crime and public safety challenges.
