In many Tennessee counties, constables are a lot like regular police officers, but with a few major differences: They get paid very little, if anything, are required to have very little training, and don't have a superior.
Through the years, different states have given the office different powers, and some states have dropped the position altogether.

And in rural Sequatchie County, the sheriff's department still very much depends on constables to keep the community safe.
