The letter was typed and contains several instances of white out. Carl probably typed the letter himself. If Carl was really serious about suing me, I would have received a letter from an attorney. Judging from the lack of any reference to Psychic Warfare, Kirlian photography, psychotronics etc. in the media, Mankind Research Unlimited did not come up with anything significant. MRU was a product of Cold War paranoia, and wasted millions of taxpayer dollars, because of Russia's alleged lead in the field of Psychic Warfare. This "gap" was KGB disinformation. Russia never had a psychic secret weapon. The Soviet Union collapsed. Books like "Psychic Discoveries Behind the Iron Curtain" were probably an unwitting part of a KGB Operation to get the United States to waste it's resources investigating phenomenon that just don't exist. Psychic phenomenon and religious phenomenon share one thing in common - a lack of evidence to substantiate their existence.
The story of Mankind Research is the story of the paranoia of the Cold War.
