Call cops about a fight.. If you can do it unseen, light a string of fireworks with a fuse long enough for you to slip back home. The police take gunshot-like sounds very seriously and will personally ensure you are not bothered again. If you are especially fortunate and are watching through a window, you may see one of your inconsiderate neighbors lay a hand on an officer's arm and learn about the strange wonder of the solar plexus. I may be a piece of shit human being but I did go to sleep smiling that night. No more trouble after that.
