The behavior in Ferguson is like what happened when protests in Cairo, Libya, Syria, Kiev (etc) got out of control. The administration demanded that those protests not be stopped, and went all the way toppling govs, with the violence escalated by probably contrived violence blamed on the gov.
So logically how does the gov not allow the protestors to overthrow the gov if that's what the leaders and those inciting them want? Quite a box the idiots in DC have put us in.
American Spring?
