I've always believed or been told that under hypnosis people wont do something which is against their conscience or nature, however recently Derren Brown hypnotised someone to do exactly that, they staged an assasination with blanks, a firearm, a celebrity victim and a shooter who couldnt recall the event.
Now the story that they use in the TV show is the shooter of Robert Kennedy who alledges he has no recollection of the shooting and conspiracy theorists suggest was programmed by the CIA. However, I thought about the shooting of John Lennon and also the shooting of UK news broadcaster Jill Dando.
Thats before you consider 9/11, The Oklahoma City Bombing, other incidents like that.
It also made me wonder, was there a time when people were less suggestible or had a stronger character and therefore would have proven much more resistant to this kind of thing?
