Martin Luther King Junior (1929–1968) líder do movimento dos direitos civis dos negros nos Estados Unidos
"Through violence you may murder a murderer but you can't murder murder. Through violence you may murder a liar but you can't establish truth. Through violence you may murder a hater, but you can't murder hate. Darkness cannot put out darkness. Only light can do that." <br class="br">Fonte: Discurso "Where do we go from here?" http://www.hartford-hwp.com/archives/45a/062.html (16 de agosto de 1967)
