Query: What proportion of Tennessee counties recognize their Sheriff as their head law enforcement official?
Context: Tennessee's Constitution requires that each County have an elected Sheriff. In 94 of the 95 counties the Sheriff is the chief law enforcement officer in the county and has jurisdiction over the county as a whole. Each Sheriff's Office is responsible for warrant service, court security, jail operations and primary law enforcement in the unincorporated areas of a county as well as providing support to the municipal police departments.
