A quick note as a contribution to the neverending (and productive) "violence vs. nonviolence" debate: the fellow swinging fists at the cops near the end is not, as it first appears, just a yob out to mess with the police. He is defending someone knocked down onto the ground by police watercannon as the line of cops advances, although this might escape your notice at first because of the compression on the video. Do a slow-motion frame by frame thing (use the arrow keys on your keyboard) at 3:24 to see this.
