- African Americans rioted against racial injustice.
- Immigrant workers in New York City rioted against the military draft.
- Working-class North Africans in Paris rioted to protest the death of two youngsters at the hands of the police.
- Tiananmen square intellectuals and students rioted for democratic reform.
Here, though, we riot when our local sports team beats a rival team, not in the finals, or the semifinals, but in the quarterfinals.
Whether it's actual hockey fans or anarchists using the crowd as a cover is anyone's guess, although the image gallery over at Fagstein's blog has an image of a hockey-flag waving fan next to a marijuana-tshirt-wearing delinquent, so maybe they're in cahoots! ;)
