Your right that is pretty weird, since they really don't know what just happened. Plus it is their job to help the person if need be not sit back and do nothing.
Also how are they communist? was this like one of those small 3rd party Communist groups that showed up at occupy or is it just one of those few paranoid crazy's again calling everything that isn't on there side a communist, socialist, or nazi or some mix of all three which makes the least sense.
Troll much boyo?
Brick thrown by itself? or are you going to claim the cops threw the brick?
Do tell us the specific rules those Officers were given that day? what are they allowed to respond to were there other Officers who would handle injured, arrested, breakthroughs of the perimeter, etc.
Small Communist groups? yep and small violent groups took over Occupy Oakland right, and the larger unicorn riding element could do nothing to stop it?
