"We can never be satisfied as long as the negro is the victim of the unspeakable horrors of police brutality. We can never be satisfied as long as our bodies, heavy with fatigue of travel, cannot gain lodging in the motels of the highways and hotels of the cities. We cannot be satisfied as long as the negro's basic mobility is from a smaller ghetto to a larger one. We can never be satisfied as long as our children are stripped of their selfhood and robbed of their dignity by signs stating "for whites only".
-- Martin Luther King, "I Have A Dream"
