There is a significant amount of police violence in guerrilla warfare-like situations. There is some blood in scenes where medical attention is given and significant terror scenes with gunfire and grenades.
In one scene, armored police beat and kick a man until his head opens and blood and brain matter pour onto the concrete. In another scene, a group of rioters surround a pair of armored police operatives, striking and knocking them down, kicking them repeatedly, before the pair manage to escape.
