I think we all know that if a community actually did that, the police would turn out in full force to stop it, and there'd be no handwringing or Political Correctness or restraint, because the demographic that would be doing it is not of a protected class that must be treated with kid gloves.
Best we could probably manage would be a network of like-minded volunteer people running 24/7 armed watch on the property and reacting defensively if anything happened. And hopefully the low-life/ghetto attitudes of those who might want revenge would age them out of the system through prison, death, etc. and the odds of them moving on or forgetting are sufficiently high.
That the angry party could only manage a drive by with a shotgun is hopefully a good sign, that it's the best they can do.
