The county sheriff is a Florida constitutional officer and a part of the state judicial branch. The sheriff has a duty to enforce both the Florida Constitution and Florida state laws and statutes, and to provide for the security, safety and well-being of its citizens. This is accomplished through the delivery of law enforcement services, the operation of the county jail, and the provision of court security.

The Sheriff is vested with the ability to appoint and direct deputies who will act in his name and office to enforce the appropriate and applicable laws of the State of Florida. Those deputies of the County Sheriff's Office who are Certified Law Enforcement officers must maintain a thorough working knowledge of the laws they enforce and the underlying principles from which they emanate.
