"Did the FBI send a letter and audio tapes from a wiretap to MLK jr. telling him to commit suicide or they would release information?"

We will have to see how this works out, but the explicit denials are easier to control for IMHO.

Reminds me of the old joke:

     A Russian and an American get on a plane in Moscow and get to talking. 
     The Russian says he works for the Kremlin and he's on his way to go learn American propaganda techniques.

     "What American propaganda techniques?" asks the American.

     "Exactly," the Russian replies.

That remind me of the quote "The totalitarian system of thought control is far less effective than the democratic one"

Full quote (Radical Priorities, Noam Chomsky, C.P. Otero)

> “The totalitarian system of thought control is far less effective than the democratic one, since the official doctrine parroted by the intellectuals at the service of the state is readily identifiable as pure propaganda, and this helps free the mind.” In contrast, he writes, “the democratic system seeks to determine and limit the entire spectrum of thought by leaving the fundamental assumptions unexpressed. They are presupposed but not asserted.”
