I've had the misfortune of living in university towns when the school team was in the final playoffs of something or other -- in both situations, the school won the championship and then the students and fans took to the streets and smashed windows and overturned cars.

I can understand being happy that your team won or being disappointed that your team lost, but I don't see the point of trashing your own backyard because a group of people who were not you played a game either better or worse than another group of people who were not you. The angry Canucks fans were treating Vancouver like an invading army would -- forget terrorist threats, just have a sports team lose -- or win! -- and you can get the city to bring itself down.
