If I'm not in a gang, and I'm walking down the street, and someone punches me in the face, who do you have a fight with? Me! You keep punching me in the face, probably. But if I'm in a gang, and you punch me in the face, now what's the problem? You might get away with punching me two more times tonight, but guess who's going to be at your house tomorrow? You don't want to see those guys. They're huge.
