Martin Luther King gave this speech on 3 April 1968 at the Church of God in Christ, in Memphis, Tennessee. The last part of this speech in particular seems eerily prophetic.
He was assassinated the next day on 4 April 1968.
"Where such a shift in power is in favor of the governing elite, Power will achieve its murderous potential. It simply waits for an excuse, an event of some sort, an assassination, a massacre in a neighboring country, an attempted coup, a famine, or a natural disaster, to justify the beginning of murder en masse. Most state sponsored murder occurs under the cover of war, revolution, or guerrilla war, or in their aftermath."
