This is an important book that explains with vivid detail how the police are led to perform improper and illegal actions in their fight against crime by the values, ethos, structure and customs of the very institutions within which they operate. It bravely broadens the subject of police mis-behavior from corruption, which can be dismissed as a private moral failing, to pervasive patterns of official action - referred to as 'structural deviance' - such as arresting, charging, harassing, and warning.
