Using primary empirical studies and extensive, in-depth interviews, this volume draws on nearly two years of field research into how minorities experience racial profiling by police authorities. The book examines what racial profiling is, its historical context, and how formal legal codes and public policy generally define it. It discusses the best methods of data collection, the advantages of collecting racial profiling data, data analysis, and methods of determining the validity of the data. The author also explores the impact of pretextual stops and the effect of Whren v. United States.
