Why wait for the authorities????
In one neighborhood I lived in, I and my neighbors were instrumental in getting a family out of a Section 8 rental. They were running a crack house.
I was told by the community association president that word on the street was that I had better watch my step. I told her to put the word out on the street that I shoot to disable. I would also sit on my front porch and clean my weapons. Never heard anything else about it.
Keep in mind, these types of 'men' go for easy targets. They prefer elderly, women and disabled and did it in groups.
There was another recent story that a group of scum were trying to car jack a Vet in his van. They were even beating him with his own cane. He pulled out a firearm and killed the one guy. A little street justice works too.
