Well, the best I can do is assure you that this type of action is only taken in severe and on-going disruption. Landlords around here are MUCH more careful about whom they rent to.
I have neighbors who have spent the last 3 months taking shifts at night to watch and protect their own and the property of their closest neighbors because the police insist that if they didn't see it, it didn't happen. Kids under the age of 15 are given less than a wrist slap. One kid stole a neighbor's car and set it on fire. He is 13. A girl planted a pipe bomb next to someone's house. She is 12.
It was after the pipe bomb next to the house that the neighbors started keeping watch. Tell me you would put up with this on your street without using everything at your disposal to stop it.
By the way, the Police Chief dismisses our concern because we don't have anyone being shot. Yeah? Not yet.
So then your real problem is that the police are not doing there Job.
