The whole thing is really quite sad.
In terms of loyalties, one might point out that there are more Canadian players on the Bruins then there are on the Canuks. There's hardly any disloyalty in being a Boston fan.
As for the guy lighting the car on fire, I expect he is in some real trouble. He will go to federal prison and perhaps for a long time.
It's probably not the same car (although it might be), but the intent is clearly the same.
It might also be pointed out that the instigators all wore masks. Most of the pictures are of Canucks fans, who were not wearing masks, and who were at the hockey game. Regardless of who started the riot, there is no question that fans at the game joined in.

In defending something like this, a person is really no better than those who actually participated.
