Nah. Programming someone into being an assassin is just fantasy. Right.
I watched this show on Discovery last week. They were attempting to prove or disprove that a person could be hypnotized to commit an assassination. If the show is to be believed they proved it possible.
Training For Assassination - Hypnosis
That is a short Youtube of the forensic hypnotist who was a part of the experiment. Under the video are a number of links to further info.
That is a link to the IMDB on the Discovery show Curiosity and the Episode "Brainwashed." I don't know where to see it other than to find it airing on Discovery but it was interesting. Not totally convinced it was real but they presented it as such.
