An Introduction to American Policing demonstrates the quest to maintain both public safety and freedom by providing a balanced yet critical investigation of police history and theory. It connects criminal justice, criminology, and law enforcement knowledge to the progress of the police community. Case studies, narratives from violators, and current research coverage help students recognize the central theories and practical (documented) realities of American law enforcement. Students are encouraged to consider the way some believe policing 'should be' while examining evidence about the 'way it is.' This text will also provide a current description of local and state police organization partnerships with federal organizations and of the efforts accomplished by federal law enforcement agencies including the Department of Homeland Securities (DHS). An Introduction to American Policing helps students learn good judgment and combines scholarly theory with practical police experience to equip your students with the information they need to become successful police officers.
