A sheriff is a law enforcement officer who is typically elected to serve a specific county or jurisdiction. They are responsible for enforcing laws, maintaining order, and protecting the residents of their community. Sheriffs have the authority to investigate crimes, make arrests, and patrol their assigned areas. In addition to their law enforcement duties, sheriffs often oversee the operation of county jails and provide security for courts. They play a vital role in the criminal justice system and work closely with other agencies to ensure public safety.
