Ahhhh, from Dr. King's Book entitled "Stride Toward Freedom" (1957):

" Violence as a way of achieving racial justice is both impractical and immoral. It is impractical because it is a descending spiril ending in destruction for all. The old law of an eye for and eye leaves everybody blind. It is immoral because it seeks to humiliate the opponent rather than win his understanding; it seeks to annililate rather than convert. Violence is immoral because it thrives on hatred rather than love. It destroys community and makes brotherhood impossible. It leaves society in monologue rather than dialogue. Violence ends by defeating itself. It creates bitterness in the survivors and brutality in the destroyers. A voice echoes though time saying to every potential Peter, "Put up your sword." History is cluttered with the wreckage of nations that failed to follow this command."
