"Gleeful about the raging riots that held England captive this week, the tweet has gone out to activists and disaffected youth to occupy wall street Sept 17 today. Social Networks FaceBook and Twitter are abuzz with plans for coming anarchy on U.S. soil.
The Days of Rage will continue beyond the occupation of Wall Street with activists being told bring your tent.

The original "Day(s) of Rage"
Days of Rage riots (1969)
The Days of Rage riots in Chicago took place over a 4-day period beginning October 8, 1969, after members of the Weathermen, a militant offshoot of the Students for a Democratic Society, converged on the city to confront police in the streets in response to the trial of the group of anti-Vietnam War activists known as the "Chicago Eight".

A liberal application of automatic weapons fire would have been justified, and could have cut the days down to one.
