The police are law enforcement officers who usually take an oath (make a promise) to protect and serve their communities. Police officers—or collectively, police departments—enforce laws, investigate potential crimes, and make arrests.
In Tennessee, as in other states, police officers are sworn law enforcement officials who take an oath to protect and serve the public. They are responsible for enforcing state laws and local ordinances. Their duties include patrolling communities to deter and detect crime, conducting investigations into criminal activity, and apprehending individuals suspected of committing offenses. Police departments, which are comprised of these officers, operate at various levels including municipal (city police), county (sheriff's departments), and state (Tennessee Highway Patrol). Each department works within a framework of laws and regulations designed to ensure public safety and uphold constitutional rights. The Tennessee Peace Officer Standards and Training (POST) Commission is responsible for setting standards and providing training for law enforcement personnel in the state.
