NIJ is the research, development, and evaluation arm of the U.S. Justice Department. NIJ has a long history of supporting high-quality, high-impact research in policing. NIJ's investments in policing are made under the principle that the successful implementation of evidence-based policing tactics and operations depends on the development of rigorous, tested evidence that meets law enforcement's needs and challenges. NIJ supports research that examines how community- and problem-oriented policing strategies can be used to assist communities in addressing crime and disorder issues and in improving relationships between police and the communities they serve. Most recently, NIJ published the first body-worn camera market survey and implementation guide, and is currently funding evaluations of this technology. NIJ is guided in its investments by the recommendations (six "pillars") of the President's Task Force on 21st Century Policing. The current report provides a few examples of NIJ's key investments under the following six pillars of the task force: building trust and legitimacy; policy and oversight; technology and social media; advancing policing; community policing and crime reduction; training and education; and officer wellness and safety.
