One of Nixon's chief advisers admitted in an interview years later that the war on drugs was explicitly targeted at black people[0]. Criminalizing blacks was a primary objective of this policy.
This is the same quote as above. Reporter does interview, waits until the guy dies, then says “he said this”, while people who knew him said “I don’t think so”.
It likely was a motive, but it doesn't necessarily make the quote real. I have trouble believing Nixon or his advisors would give a supervillain monologue like that, personally, even if those were their exact intentions.
read the whole thread man. I don't think anyone here doubts that drug enforcement in America is racially motivated, but you're the third person to cite that very dubious quote.
