"We’ve got to organize. We’ve got to organize so effectively and so well and engage in such powerful, creative protest that there will not be a power in the world that can stop us and that can afford to ignore us… Our power lies in our ability to unite around concrete programs. Our power lies in our ability to say nonviolently that we aren’t gonna take it any longer. You see the chief problem with a riot is that it can always be halted by a superior force. But I know another weapon that the National Guard can’t stop."
 

–Martin Luther King Jr., Cleveland, OH (April 26, 1967)
