The third article discusses using knowledge and teamwork (involving U.S. attorneys, community leaders, and researchers, among others) to identify and solve specific crime problems. It reviews a five-city pilot initiative that built on lessons learned in other communities where crime was dropping. The fourth article describes the National Institute of Justice’s John B. Pickett Criminal Justice Policy and Management Fellowship Program.
