LOS ANGELES, November 9, 2004 - At 7:50 PM two armored tanks showed up at an anti-war protest in front of the federal building in Westwood. The tanks circled the block twice, the second time parking themselves in the street and directly in front of the area where most of the protesters were gathered. Enraged, some of the people attempted to block the tanks, but police quickly cleared the street. The people continued to protest the presence of the tanks, but about ten minutes the tanks drove off. It is unclear as to why the tanks were deployed to this location.
So who ordered that? If it was a local decision, shouldn't people be concerned that a local official has the authority to order tanks onto the streets of LA?
There is a video.
From what I hear the tanks had driven up the San Diego freeway from Camp Pendleton near San Diego in order to participate in a Veterans Day parade in Westwood. They were headed to the nearby National Guard armory. When they got off at the wrong exit they happened to run into this protest by accident. Probably coincidence, considering there was little outward intimidation from the soldiers onboard, but a disconcerting coincidence nonetheless.
