chaos. you don't have to hear the gunshots to feel the intensity erupt outside the twin peeks restaurant. some bikers duck for cover. in the background you can see others run from the slaughter and perhaps the most graphic portion of the surveillance tape a man in a red bandanna sneaks up on another biker and appears to strike him in the throat. the two wrestle on the ground before a third biker joins in. the man in the red bandanna is struck several times in the head while on the ground. he is stomped at least once. he lies motionless as the man he was fighting walk off screen. in the foreground, more bikers run from what seems to be the epi center of the violence. one man checks the blood dripping from his arm. another falls to the ground after appearing to be shot. the agony is all around. according to a document passed on to cnn by a source close to the case, four of the nine bikers who died were hit by two three caliber ammunition. what started this all? it's up for debate.
