This book is the most systematic, comprehensive and philosophically sophisticated discussion of police ethics yet published. It offers an in-depth analysis of the ethical values that police, as servants of the community, should uphold as they go about their task. The book considers the foundations and purpose of police authority in broad terms but also tackles specific problems such as accountability, the use of force, deceptive stratagems used to gain information or trap the criminally intentioned, corruption, and the tension between personal values and communal concerns.
