From Paul DiMaggio, Professor of Sociology, New York University: “Predict and Surveil is a breakthrough book, a close-up, ethnographically grounded, examination of how urban police departments are using the power of big data to try to anticipate crime and outflank criminals and how, in so doing, they risk reproducing inequality by embedding results of past discrimination inside opaque algorithms. At a moment when urban policing has come under unprecedented scrutiny, this volume provides indispensable insight into a critical element, big data, that could replace due process with guilt by association–or, if used properly, could help reduce discrimination and open policing to democratic control.”.
