"If even the earliest attempts at centralized police forces would have alarmed the founders, today's policing would have terrified them. Today in America SWAT teams violently smash into private homes more than 100 times per day. The vast majority of these raids are to enforce laws against consensual crimes. In many cities, police departments have given up the traditional blue uniforms for 'battle dress uniforms' modeled after soldier attire. Police departments across the country now sport armored personnel carriers designed for use on a battlefield. Some have helicopters, tanks and Humvees. They carry military-grade weapons. Most of this equipment comes from the military itself. Many SWAT teams today are trained by current and former personnel from special forces units like the Navy SEALs or Army Rangers... At the time the Third Amendment was ratified, the images and memories of British troops in Boston and other cities were still fresh, and the clashes with colonists that drew the country into war still evoked strong emotions. What we might call the 'symbolic Third Amendment' wasn't just a prohibition on peacetime quartering, but a more robust expression of the threat that standing armies pose to free societies. It represented a long-standing, deeply ingrained resistance to armies patrolling American streets and policing American communities."
