David M. Kennedy is the director of the Center for Crime Prevention and Control and professor of anthropology at John Jay College of Criminal Justice in New York City. From 1993 through 2004, he was a senior researcher and adjunct professor at the Program in Criminal Justice Policy and Management, Kennedy School of Government, Harvard University. His work focuses on strategies for assisting troubled communities. He has written and consulted extensively in the areas of community and problem solving policing; police corruption; and neighborhood revitalization. He has performed field work in police departments and troubled communities in many American cities, London, Sydney, and Puerto Rico. He is the co-author of a seminal work on community policing, Beyond 911: A New Era for Policing, and numerous articles on police management, illicit drug markets, illicit firearms markets, youth violence, and deterrence theory, including editorials in the New York Times, Washington Post, and elsewhere. He has advised the Justice Department, the Department of the Treasury, the Bureau of Alcohol, Tobacco, and Firearms, the Office of National Drug Control Policy, and the White House on these issues. He directed the Boston Gun Project, a ground-breaking problem-solving policing exercise aimed at serious youth violence. Its chief intervention, Operation Ceasefire, was implemented in mid-1996 and appears to have been responsible for a more than sixty per cent reduction in homicide victimization among those age 24 and under citywide. Operation Ceasefire won the Ford Foundation Innovations in Government award; the Herman Goldstein International Award for Problem Oriented Policing, and the International Association of Chiefs of Police Webber Seavey Award. He has contributed to similar homicide prevention exercises in Minneapolis, Indianapolis, Baltimore, Pittsburgh, High Point and Winston-Salem, North Carolina, San Joaquin County, California, San Francisco, Washington DC, and elsewhere, and helped design and field the Justice Department’s Strategic Approaches to Community Safety Initiative. He helped design the Youth Crime Gun Interdiction Initiative, launched by the Clinton Administration in 1996, for which he received a director’s commendation from the Bureau of Alcohol, Tobacco, and Firearms. He designed, with law enforcement and community partners, the “High Point” drug market elimination strategy, which is now being implemented in a series of cities with support from the Justice Department and the National Urban League..
