In recent years, racial profiling has drawn the attention of state and federal governments. In this book, racial profiling is defined as the practice of targeting individuals for police or security interdiction, detention, or other disparate treatment based primarily on their race, ethnicity, or national origin in the belief that certain minority groups are more likely to engage in unlawful behaviour. Assertions that law enforcement personnel at all levels unfairly target certain racial and ethnic groups, particularly but not exclusively for traffic stops and searches, have raised concerns about violations of the Constitution. The major debate on racial profiling centres on whether the practice should be prohibited entirely and whether data on traffic stops and searches should be collected to determine if the practice is occurring. This book gathers presents the major issues, available data, and analyses important to understanding on the most dangerous and divisive practices of our time.
