Been following the Ferguson, MO shooting and aftermath (on Twitter, since it seems below the radar of cable news).  The whole situation is unimaginable for those of us in the quiet, homogenous naivety of Utah and the west.  The clip that has stuck with me from weekend coverage most is the police officer on camera, heard clearly, speaking to protestors, growling "Bring it on, you fucking animals."

A lot hasn't changed.  MLKjr, 1967, The Other America:

Let me say as I've always said, and I will always continue to say, that riots are socially destructive and self-defeating. I'm still convinced that nonviolence is the most potent weapon available to oppressed people in their struggle for freedom and justice. I feel that violence will only create more social problems than they will solve. That in a real sense it is impracticable for the Negro to even think of mounting a violent revolution in the United States. So I will continue to condemn riots, and continue to say to my brothers and sisters that this is not the way. And continue to affirm that there is another way.

But at the same time, it is as necessary for me to be as vigorous in condemning the conditions which cause persons to feel that they must engage in riotous activities as it is for me to condemn riots. I think America must see that riots do not develop out of thin air. Certain conditions continue to exist in our society which must be condemned as vigorously as we condemn riots. But in the final analysis, a riot is the language of the unheard. And what is it that America has failed to hear?
