Evidence-Based Policing: The Importance of Research and Evidence

July 2018
Series
Research for the Real World
NIJ’s two Law Enforcement Advancing Data and Science programs encourage law enforcement officers and agencies to use data and research to inform their policies and practices. This panel convened leading practitioners and researchers to discuss evidence-based policing for an audience that includes the next generation of U.S. policing leadership. Panelists come from a variety of backgrounds and will draw from on-the-ground experience to discuss evidence-based policing as it relates to law enforcement training curriculums, practitioner-led trials, research clearinghouses, and other topics.
