Taking a big picture perspective, Law Enforcement in the 21st Century, 3e examines policing practices and how law enforcement agencies relate to one another and the entire criminal justice system. Streamlined in this edition, the book emphasizes linkages across law enforcement jurisdictions and how to develop a coordinated approach to information sharing and strategy development. Unique chapters appear on multicultural communities and new technologies used to assist police in prevention, communication and control. Linkages and Law Enforcement exercises and a new MyCrimeKit website encourage students to explore the changing dynamics and nature of policing within its larger contexts.
