Civilian warfare and assistance hint
Go to a car when a man is in it (this will not work with a woman) while making sure that there are other pedestrians around you on the sidewalks. Push or punch the car around the front, then let the man exit and beat you up a little bit. Some of the male pedestrians will then rush to help you while punching or pulling out knives on your attacker. Sometimes, if an officer is around, he will arrest the attacker.
