Edit: Ouch, looks like quite a few people here do. Do y'all really think that's the best way to effect social and political change? A minority of Americans screaming louder and using terrorism to vent their spleens won't solve the issue. In a democracy, everyone must focus on getting more people to vote for different policies to effect change.
There is justifiable outrage. I do not condone wanton destruction and arson, but disruptive protests work in a way that peaceful ones alone do not.
