Violence in Vancouver

The Winter Olympics in Vancouver have not got off to a good start.

First, there was the death of Georgian luger Nodar Kumaritashvili.

Today, violence broke out in downtown Vancouver. Riot police had to be called in to quell hooligans who broke shop windows, committed acts of vandalism and menaced pedestrians.

One can only hope it stops there. But you know that these things often come in threes.
