Power and Authority: Profiles of Contemporary Law Enforcement and Corrections Applications presents students with an exploration of the challenges to the power and authority of the criminal justice discipline that professionals may face during the course of their careers. The text opens with an introductory chapter that clarifies the differences between power and authority, introduces students to ethics-based theory, presents theoretical considerations, and speaks to the abuse of power and authority. The chapters that follow examine specific challenges to the power and authority of the criminal justice profession. Topics explored include excessive use of force, extortion, sexual harassment and sexual misconduct, aiding in an escape, and coercion. The final chapter provides examples of active policies used in diverse areas of the United States including El Paso, Las Vegas, Maryland, and Eau Claire.
