The Posse Comitatus

The Posse Comitatus Act, enacted in 1878, restricts the U.S. military from acting as law enforcement within the United States. Its purpose is to prevent the armed forces from interfering in civilian policing unless explicitly authorized by Congress or the Constitution. The law aims to protect citizens' rights and maintain civilian control over military power. However, exceptions exist, such as in cases of emergencies or when authorized by law, ensuring that the military supports civil authorities without overstepping its boundaries.
