Well, as far as I am concerned, the police had no business being there in the first place. They want to live like animals, fine! Just cordon off the area, keep them in and decent people out. Unless I was armed I would not go near the place.
Yeah; like they did in Watts? Where they burn down their houses, then WE (the taxpayers) pay for their new digs? That makes sense....
Shoot the bastards on sight when found breaking the law, and you eliminate chronic, repeat offenders.
