I've spent a lot of time living in poorer areas and I can tell you from experience, noise ordinances are not effective. It'll take months or years for Cletus to work his way through the court system for noise pollution, and in the meantime, he's not going to be very happy with his neighbors for reporting him. You'd better hope he doesn't do something in retaliation! Oh, and while you're twiddling your thumbs waiting for his eviction, ten more will move in down the street. You know, because you magically made all the houses $40,000.
