The problem with the hands up, don't shoot narrative used by those in Ferguson is even when it was proven that Michael Brown didn't have his hands up, the excuse making rioters and looters continued to use it as a way to steal and destroy.
The media is the problem. They emphasize things like witnesses claiming Brown had hid hands up and it stirs up those wanting an EXCUSE to loot and destroy. When it's proven wrong, those doing the looting don't change their minds to the truth.
So when they learn the truth, and still riot/steal shit. Doesn't that prove that they don't care about the cause, and just want to cause destruction, get more free shit.
