In Cop Watch: Spectators, Social Media, and Police Reform, renowned social psychologist Hans Toch takes stock of the vast changes in police procedures that have occurred over the last half-century by examining the evolving role of spectators to police-citizen interactions. This sympathetic and informed analysis details the concerns of both disgruntled citizens and unsettled police. Their interactions are played out on a broad stage, from 1960s riots and Kerner Commission findings, to 2011 accusations of police brutality in Seattle. In this unflinching examination of the power of the crowd and society to shape police practice, Toch provides a uniquely compelling look at the struggles and complexities of policing in a volatile world.
