This book examines  the timely issue of police stops as a public and political issue, focussing on the European states. Contrary to much other work it focuses on wider Europe and the social and political context in which the police practice of stopping citizens emerges, develops and can be curtailed. More specifically, the volume analyses public controversies about police stops, i.e. events in which conflicts emerge about how the performance of police stops is explained and justified.  This book stems from an EU COST Action research network on Police Stops which engages academics and practitioners from 29 countries. It appeals to those in law, criminology and policing studies with some potential for wider interest in cultural studies/history and public policy/politics, as well as to practitioners in police scrutiny, oversight and other professional bodies and in training organisations.
