Sheriff
In principle, a sheriff is a legal official with responsibility for a "shire", i.e. county. In practice, the specific combination of legal, political and ceremonial duties of a sheriff varies greatly from country to country.
In the United States of America, a sheriff is a sworn law enforcement officer and the duties of his/her office vary across states and counties. A sheriff is generally an elected county official, with duties that typically include policing unincorporated areas, maintaining county jails, providing security to courts in the county, and (in some states) serving warrants and court papers. In addition to these policing and correction services, a sheriff is often responsible for enforcing civil law within his/her jurisdiction.
A sheriff (or High sheriff) is a ceremonial county or city official in England, Wales, Northern Ireland, and India.
In Scotland, sheriffs are judges.
In the Republic of Ireland, sheriffs are legal officials similar to bailiffs in some counties and in the cities of Dublin and Cork.
