Riots are horrible. It's now thought the riots in Vancouver were pushed to new levels by anarchists who brought hammers and Molotov cocktails Into the fan zone to ramp up the behavior. Whether it's Battle For Seattle or the Olympics, Anarchists in the PNW are pretty well entrenched. I remember the EArth Liberation Front destroyed a building at Wash. St. University to release veterinary animals which killed most of them when they were released.
