I don't know if you are being sarcastic in your first 2 comments:
"It seems that in a population that is prone to riot, couldn't they get it right just this once and riot against their own criminal element especially when they are raping and murdering their own children?
I guess the paid instigators weren't there to direct them?"
If you lived through the race riots in CA then you know the truth. The thugs take advantage of situations. That this was not predicted or expected is negligence on the part of the local and state officials. They know the area the best.
The race riots I was familiar with were not filled with thugs, just the general population living in that area going around breaking and burning things. No one ever really could figure out the reason. They just seemed to spontaneously start.
Seems like they could harness that energy for good too if needed.
