Malcolm Sparrow, who teaches at Harvard's Kennedy School and is a former British police detective, argues that other factors in the development of police theory and practice over the last twenty-five years have also played a major role in contributing to tragedies and to a great many other cases involving excessive police force and community alienation. Whatever happened to community and problem-oriented policing? How can the current crisis in policing can be traced to failures of reform? The police shooting of an unarmed young black man in the St. Louis suburb of Ferguson, Missouri, in August 2014 sparked riots and the beginning of a national conversation on race and policing. Much of the ensuing discussion has focused on the persistence of racial disparities and the extraordinarily high rate at which American police kill civilians (an average of roughly three per day). Sparrow shows how the core ideas of community and problem-solving policing have failed to thrive. In many police departments these foundational ideas have been reduced to mere rhetoric. The result is heavy reliance on narrow quantitative metrics, where police define how well they are doing by tallying up traffic tickets issued (Ferguson), or arrests made for petty crimes (in New York). Sparrow's analysis shows what it will take for police departments to escape their narrow focus and perverse metrics and turn back to making public safety and public cooperation their primary goals. Police, according to Sparrow, are in the risk-control business and need to grasp the fundamental nature of that challenge and develop a much more sophisticated understanding of its implications for mission, methods, measurement, partnerships, and analysis.
