What case does dr. king make against “well timed” action?

We know through painful experience that freedom is never voluntarily given by the oppressor; it must be demanded by the oppressed. Frankly I have never yet engaged in a direct action movement that was "well timed," according to the timetable of those who have not suffered unduly from the disease of segregation. For years now I have heard the word "Wait!" It rings in the ear of every Negro with a piercing familiarity. This "wait" has almost always meant "never." We must come to see with the distinguished jurist of yesterday that "justice too long delayed is justice denied."
