Full Definition Of Posse Comitatus Act

The Posse Comitatus Act, enacted in 1878, is a federal law that limits the involvement of the Army and Air Force in civilian law enforcement activities. It prohibits these military branches from making arrests, conducting searches, or seizing evidence in most cases. However, the law does not apply to the Navy, National Guard, and Coast Guard. In situations like riots, where assistance is needed to control the situation, the Army cannot be called upon, but the National Guard can be.

This ensures that the military is not utilised to infringe upon citizens’ rights or enforce laws in a manner inconsistent with the Constitution.
