Condo kids wreaking havoc?

The condo company really can't do anything. I used to work for one, and people always complained to us but all we could do was call the cops, and usually the complaint was after the fact so nothing could be done. Record them breaking the law and call the cops, then the parents will HAVE to do something, or their kids go to jail. The parents are to blame here. Don't single yourself out, in case they retaliate. You can call the cops anonymously. Find the non-emergency line to your local police station, don't tie up 911.
