This work provides an innovative new look at police ethics, including results from an updated version of the classic Police Integrity Questionnaire, including new social and technological advances. It aims to push the study of police research further, expanding on and testing police integrity theory and methodology, the relationship between community and integrity, and the influence of multiculturalism and globalization on policing and community attitudes. This work brings together experienced scholars who have used the police integrity theory and the accompanying methodology to measure police integrity in eleven countries, and provide advance and sophisticated explorations of the topic. Organized into three thematic sections, it explores the testing methodology for international comparisons, insights into police-community relations, and explores police subcultures. This innovative book will be of interest to researchers in criminology & criminal justice, particularly with an interest in policing, as well as related fields such as sociology, public policy, and comparative law.
