Police departments are municipal law enforcement agencies empowered to enforce city and state laws. These departments play a vital role in maintaining order, protecting private property and protecting the public.
Police departments only have jurisdiction in a limited geographic area. Some police are responsible for security in towns or cities, while others are responsible for patrolling university campuses or other public institutions. Police departments are responsible for issuing citations for speeding, parking and other minor violations to promote public safety.
They also investigate serious crimes, collect evidence, make arrests, and work with other law enforcement agencies in nearby jurisdictions, such as sheriffs' offices. Police departments also maintain databases of criminal records, including mugshots and police blotters. These police records help investigate and prosecute crimes and allow the public to perform background checks.
