According to what I read, Kaczynski was subjected to verbal abuse every week for about 3 years, a total of about 200 hours. I didn’t read that they gave him LSD, but they did give it to others in the MKUltra experiments, notably Frank Olson, a bacteriologist who worked for the CIA and who had become increasingly concerned about government abuses of power. He died.
It appears to me that the CIA has had morally deranged individuals operating unfettered for most and possibly all of its existence. The information I’ve gotten from wikipedia and assorted random websites may, of course, be disinformation.
The the CIA was augmented with NAZIs when it was formed out of the OSS. Russia got some of those NAZIs, we got some, and the British got some. The rocket NAZIs didn’t go to Britain.
