American law enforcement has become zero tolerant, more violent, and militarized. Local, state, and federal teams of elite paramilitary special weapons and tactic (SWAT) units regularly patrol big city streets and break into homes unannounced in search of drugs. Officers on routine patrol carry high-powered semi-automatic weapons. Virtually every law enforcement agency in the country either has its own SWAT unit or has officers who are members of a multi-jurisdictional force. The barrier between the U. S. Military and domestic law enforcement has broken down. The police have become soldiers, and military personnel now function as civilian law enforcers.
