In San Francisco, well over 5,000 protesters, having planned weeks in advance to shut down the city on "Day X" as part of Direct Action to Stop the War, blockaded the Financial District resulting in 2,200 arrests. Other protesters, marching as a black bloc, attacked and looted several military recruitment centers. A Critical Mass of cyclists also attempted to block traffic to the Bay Bridge. Approximately 300 protesters demonstrated outside of the federal building. Some of the protesters apparently began vomiting on the sidewalks and plaza areas in front of the building and behind the building. Spokespeople told reporters that it was the protesters' way of saying that war in Iraq "made them sick." Seven demonstrators were arrested after attempting to block about twenty federal employees and other visitors trying to enter the building.
