I would be a lier if I did not say that I agree, to a point. I have seen diffrent people rationalize the rioting as a statement (basicly, obey our command OR ELSE). That in itself strikes me as eerily simmilar to what they are fighting AGAINST, not to mention a non-winning strategy (how long are the authorities going to hold back and allow more looting and damage to be done?).
That said however, Ferguson is just a small example of a bigger, US wide problem of racism and brutality within many police forces.
Though the behaviour of some members of the protests is unacceptable, that is no reason to throw the baby out with the bathwater.
