A woman breaks another man's arm (we hear a crunch and see the chop without much detail), she face-palms him and kicks him. She dodges bullets discharged by other cops, throws a chair at one of them, shoots another, then chops/kicks the final one to the ground. It is assumed all those cops die. She flees from more cops, jumping off rooftops and crashing through windows, and runs to a pay phone in order to get out of the situation. A garbage truck plows down the phone booth but she lives .
