I would say this is shocking, except it's not really.
I have to agree sirdennis, what do they expect? Guns pretty much freely available, fairly frequent shooting of black people by white police officers....it was almost inevitable.
It just feels like a matter of time before anarchy starts to break out. Racism is alive and well the world over, and is pushing its way to the forefront over here as well.
Sad, depressing and very worrying times.
