Police science
Police science or police studies is the study of police work. It is a subfield of criminology and sociology. As an interdisciplinary science, the field includes contributions from political science, forensic science, anthropology, psychology, jurisprudence, criminal justice, human geography, correctional administration and penology. The field makes contributions to understanding of community policing, police culture, and other policing tactics or behaviors.
There was a "dizzying expansion" of police studies in the early 2000s with a large number of works being published in the field.
