This work examines in-depth the phenomenon of volunteer policing in the United States. Due to a combination of municipal budget cuts, decreased manpower, and a renewed interest in community partnership, everyday citizens are increasingly joining the police rank and file. This trend provides low-cost solutions for a number of policing problems, but also brings its own special challenges and considerations. This work provides a historical overview of volunteer police in the United States and abroad; an practical overview of volunteer programs throughout the United States including training programs, requirements and qualifications; a close examination of two central types of laws governing volunteer police units: the Stand Your Ground law and the Good Samaritan law; and overview of the dangers that can face volunteer police units, and a comparative analysis with volunteer programs worldwide. It will be of interest to researchers in police studies, criminal justice administration, and for policymakers and practitioners working with police organization and training.
