What does the Posse Comitatus Act symbolize?

The Posse Comitatus Act symbolizes the separation of civilian affairs from military influence by prohibiting the use of the military for domestic law enforcement without specific authorization from Congress. This act was established in the late 19th century in response to concerns about military intervention in civilian matters, particularly during reconstruction after the Civil War. By reinforcing the idea that the military should not engage in policing activities in the civilian realm, the Posse Comitatus Act helps maintain a balance of power between military and civilian authority, ensuring that civilian governance remains intact and that military force is not used to suppress civil liberties or law enforcement. This principle is foundational to the United States' approach to the relationship between military and civilian entities.
