Because They Marched

It's unimaginable today, even for a generation that saw the Twin Towers fall and the Pentagon attacked. It's unimaginable because in 1814 enemies didn't fly overhead, they marched through the streets; and for 26 hours in August, the British enemy marched through Washington, D.C. and set fire to government buildings, including the U.S. Capitol and the White House.

In October 1969, hundreds of young people wielding lead pipes and clad in football helmets marched through an upscale Chicago shopping district, pummeling parked cars and smashing shop windows. Thus began the "Days of Rage," the first demonstration of the Weathermen, later known as the Weather Underground.
