We had one in Pullman the Greeks attacked the dorm rats maybe 2000 3000 people involved. The cops showed up and their cars got pelted, they backed out and a few minutes later the cops showed up on foot filled armed with snowballs and fought their way down the middle for a fee minutes and retreated . But that was the old days before everyone turned into a mommie and the cops turned into storm troopers. We had a code back then you didn't attack anyone that was not armed or participating unless they mouthed off.
