Via The Sun:
The riots followed the alleged rape with a baton of a black youth by police. Even if this story was true - it just might, I haven't looked into it too closely, and besides, if police really did this, I doubt the victim was a choirboy - it would be no reason for 2,000 assholes to wreak havoc on an entire neighborhood.
It was not just blacks rioting. There's also reports of protesters shouting "Allahu Akbar":
By all means, bring in more "refugees"!!!
