The power of posse comitatus, meaning "power of the county," traditionally belongs to the county sheriff, allowing them to summon citizens to help enforce laws or capture criminals, as seen in Western movies. Related to this is the Posse Comitatus Act of 1878, which restricts federal military use for domestic law enforcement, but the authority to call upon the militia (National Guard) for such tasks rests with the President or state governors, depending on the circumstances, with federal troops generally excluded unless Congress or the Constitution authorizes it.

Who can enforce the Posse Comitatus Act?

The title of the act comes from the legal concept of posse comitatus, the authority under which a county sheriff, or another law officer, can conscript any able-bodied person or group to assist in keeping the peace.
