I always found these Wikipedia articles underwhelming, but listening to the CBC podcast and behind the bastards episodes on the specific victims of the program and how the scientists at McGill intentionally destroyed their brains purely through psychological torture is incredibly heart wrenching.
Also interesting that there's evidence that the Unabomber was a victim of some of the mkultra program.
I agree, the Wikipedia articles on MKUltra definitely have a somewhat conservative (not politically) take.
The Unabomber connection is also interesting. Have you read the book CHAOS by Tom O'Neill? It makes a very good case that Charles Manson and the Family may have also been involved (as subjects) with MKUltra and COINTELPRO.
I came to post exactly that. The proven and acknowledged aspects of MKUltra are frightening, without even getting into the conspiratorial accusations.
The page on the Church Committee is a great starting point for learning more about similar covert projects.
COINTELPRO in particular is very frightening.
