That makes no sense whatsoever. If your team wins a big sporting event do YOU get violent? No. The violence comes when people LOSE and then they act out. So it's kinda confusing when the donjohn makes such a nonsensical predictions. Unless you think that makes perfect sense in which case WHY does it make perfect sense for the winners to riot and do damage? Isn't it rather the bad-sport losers who won't be able to take it and will go out and riot and start fires and/or start shooting? Inquiring minds wanna know.
