To better understand how policing will change in the future, in 2008 the National Institute of Justice (NIJ) and Harvard's Kennedy School of Government began collaborating on the second "Executive Session on Policing and Public Safety," bringing together 28 leading law enforcement executives and academic professionals to explore issues in policing and crime control. The participants were selected based on a combination of factors, including experience, ability to work cooperatively, and potential for helping with dissemination. The expert panel examined how to influence public policy and produced many concept papers. This online resource provides access to their combined work in addressing the increasing challenges and complexities confronting law enforcement executives in the 21st century. In response, the second Executive Session produced a second series of papers in several areas including: police discipline, police science, professionalism of the police, and the changing environment of policing. As a result of their efforts, NIJ and the Kennedy School of Government are entering into Phase II to extend these discussions and explore emerging issues related to policing research, management, and policy such as: procedural justice in policing, the role of police in reducing incarceration, race relations inside police agencies, and police-community relations.
