5+ people? I have heard of one demonstrator being shot by the police in Afganistan. Who are the others?

Things have definitely gone too far. The anger are out of proportion to the insult, and this suggests to me that there are other issues at work here.

There are always those who finds it to their advantage to help trouble along. In this case I think we can find such people on both sides. Which to me is a strong argument for staying calm and sceptical.
