In 2017, the Las Vegas, Nevada, Metropolitan Police Department (LVMPD) adopted a series of interventions designed to reduce gang and gun violence across Las Vegas. In partnership with the International Association of Chiefs of Police/University of Cincinnati (IACP/UC) Center for Police Research and Policy and with evaluation funding provided by the Laura and John Arnold Foundation, the LVMPD implemented three violence reduction strategies: (1) focused deterrence (offender notification sessions); (2) hot spot patrols; and (3) place network investigations (PNI), also known as place-based investigations of violent offender territories (PIVOT), which is the focus here.
