Could it be possible? Some British hypnotist says it can be done.
Real History Blog: British hypnotist shows how an ordinary person can be programmed to kill: Sirhan/RFK parallelWow. I mean, just, wow. It's one thing to believe something. It's another to know it. I used to simply believe it was possible to program someone highly hypnotizable to kill, or pretend to kill, someone else. But now I don't just believe. I know. I saw it done, on this British show.
Master hypnotist Derren Brown has a new series of shows called "The Experiment" on Channel 4 in the UK. In his season opener this year, he did a segment called "The Assassin" in which he chooses a highly hypnotizable subject and gets him, by the end of a show (filmed over, if memory serves, a two-month period), to shoot at a celebrity in a public setting where the subject was given every reason to believe he was not being filmed and that was not part of an experiment.
You simply have to watch this show. You'll never know - you'll only just believe, or disbelieve - until you see this.
