Looks like footage of a war zone. Those are populated areas and the cops are shooting automatic weapons all over the place.
Yep. The unfortunate citizens get caught in the middle. There were a lot of repercussions from this action and they have somewhat refined their tactics and succesfully pacified and occupied quite a few favelas already but the tensions in this action were very high due to the last attempt having incurred 5 police casualties including the death by a sniper bulit of their batallion comander. Drugs, cash, weapons. Bad combo.
