Policing is a profession that works at the frontier of social order and disorder. The immediate signs of disorder are crime and violence. But the key to navigating this frontier lies deeper—in poverty, gender, racism and a range of other points of social fracture. This research network addresses the evolving roles and challenges of professional policing from three perspectives: the changing nature of the profession of policing; best practices of policing in the context of community diversity; and police education and training. Its focus is on success narratives, where participants in the research network document and analyze their experiences or the experiences of others in case studies of successful policing strategies from the US or around the world.
