"The whole problem is really the blacks. The key is to devise a system that recognizes this while not appearing to." said Richard Nixon. "Look, we understood we couldn't make it illegal to be young or poor or black in the United States, but we could criminalize their common pleasure. We understood that drugs were not the health problem we were making them out to be, but it was such a perfect issue...that we couldn't resist it."
-John Ehrlichman, White House counsel to President Nixon on the rationale of the War on Drugs.
