There is no proof this was even done by drunk teenagers. That was just one neighbor's guess, since apparently there were no witnesses. It could just as easily have been a 50 year old member of the anti-war loony left.
**Clarification**: I'm not taking up for drunk teenagers.
Well, let's hope whomever did it will answer for thier ugliness one day. They can't even hold a candle to our soldeirs.
