In Edge of the Knife, noted authority Paul Chevigny draws on years of field research to investigate torture and the use of deadly force, in addition to less drastic forms of violence, in New York, Los Angeles, Sao Paulo, Buenos Aires, Mexico City, and Kingston. Chevigny, author of the classic Police Power, examines the sources of official violence and offers possibilities for controlling it. What emerges from his work is an image of police violence as a reflection of the larger order of a city, and a convincing argument for persistent government action against crime—including accountability for police violence.
