gangster kill gangster, doing society a favour. If you don't go to the dark side or fk with the locals, people won't be so free to come out and have you shot.

Not only that but they know who to go for, one fella immediately get into the car but they focused down on the 2 fellas, ignore the guy in the car. Even made sure had time to put a few rounds in the head to make sure the fella really dead.
