One thing that needs to be pointed out is that, as of the last I checked, there was only one person dead from these riots. Seems our Canadian friends are moderate even in their rioting.

One dead is hardly much of a riot in the US. Most US cities the size of Vancouver have at least one on a slab most weekends. And that without any major sporting events. For mayhem the US is still #1 among developed nations. We also lead the world in percentage incarcerated.
