This report examines the degree to which activities associated with the National Initiative for Building Community Trust and Justice – a six-city effort to promote more equitable, just, and respectful policing practices and improve relationships and trust between law enforcement and community members – yielded their intended impacts on crime rates, departmental practices, and police-community interactions. Analyses of administrative data indicated that the impacts of the interventions varied considerably by site – as did the availability and richness of sites’ data. Changes in calls for service, violent crimes, and property crimes were mixed across sites. Two of the cities observed deceases in the amount of use of force incidents, but there was no reduction in the racial disparity of those events. While rates of pedestrian and traffic stops generally declined after the start of the National Initiative’s primary activities, they ultimately returned to previous levels. In addition, arrest rates declined across sites, but no differences emerged in arrest rates by racial or ethnic characteristics. Site-specific findings and their association with National Initiative activities are discussed in detail.
