The structure of police departments in the United States

Summary

The structure of policing in the United States is diverse, encompassing sworn officers who carry badges and arrest powers, as well as non-sworn civilians who perform various support roles. There are approximately 18,000 police departments across the country, with most being small, local municipal agencies or sheriff's departments. Local law enforcement deals with criminal cases, while sheriff's departments handle broader duties, including court security and jail operations. State-level police manage highway patrols, and federal agencies enforce national laws, with major departments like the FBI and TSA addressing specialized areas like criminal investigations and national security.
