This document outlines a joint effort between the Office for Victims of Crime and the International Association of Chiefs of Police to enhance law enforcement response to victims. It introduces the organizations and describes a 21st Century Strategy that provides a framework for agencies to place victims' needs at the center of their response. The strategy involves 4 core elements - leadership, partnering, training, and performance monitoring - and agencies implement it through a 4-step process of starting, charting, implementing, and sustaining changes. Accompanying volumes provide an implementation guide, resource toolkit, and upcoming supplemental training materials.
