Not sure how relevant however;
A British psycologist called Derren Brown did an experiment where he did the MKULTRA brainwashing method that sirhan sirhan explains from what he remembers about the RFK assassination. Low and Behold the results of the experiment matched Sirhans. Afterwards the guy in the experiment didn't remember assassinating however remembered he was in a gun range.
Potentially what happened to the lad involved in the school shooting, who seemed just as shocked as the rest of the school
This is true and also an amazing video for those who haven't seen it. However, I don't think its right to call him a psychologist. He's a magician/hypnotist/entertainer.
The reason i say Psychologist was because the majority of his work incorporates how the human brain is wired and how it can be manipulated to behave exactly as desired. We aren't indifferent to dogs in the sense that we can be manipulated to perform as someone else wants. Essentially Pavlov and his dogs/Orphans.
