Hypnotized to Kill

Can someone be hypnotized to kill and not know that he had been hypnotized?
A typical example would be to dwelve into the assasination of Robert F Kennedy, when the world unfortunately only remembers JFK's assasination and the mysterious plot behind it.

Latest research into Rober F Kennedy assasination shows his assasin Sirhan was hypnotized killer.
Its a well known fact that the subject can be made to do anything under hypnosis but is it possible to make the subject do post the hypnosis? or rather can the hypnotic phenomena be carried even after the session is over?
Maybe be hard to believe but its strangely its true and the phonomenon is called POST Hypnotic Instruction.

To demonstrate that post hypnotic suggestion is true and works, a small experiment was carried out wherein the subject with selective amnesia and highly probable victim of hypnosis was taken in the study. The subject performed and revealed whatever the hypnotist wanted him to during the session. Before the end of the session however, the hypnotist asked the subject to loosen up his tie after the session is over , when he see the hypnotist wear his glasses back. Shockingly , the session was over and the hypnotist had normal conversations with the subject for a long time. When he wore his glasses back, indeed the subject started to loosen up his tie. When asked the rational explanation behind , he hesitated but somehow searched for an answer and said he felt hot inside the room.

This is what is called as the COMPULSIVE TRIAD in post hypnosis instruction therapy.
1. amnesia on the instructions given
2. compulsive need to follow the instruction under hypnosis
3. trying to find a rationalization for the post hypnotic act

Sirhan case the compulsive triad just worked like this, he was just a patsy in the whole plot.
1. he was one of the few people who is very vulnerable to hypnosis and has therefore total amnesia during the process.
2. Once he was hypnotized being a suitable candidate he could follow the instruction clearly
3. his rationalization he found was RFK was pro-israel
Sirhans was believed to be the only assasin to have shot kennedy or only one who was reprimanded

However a lot of questions remain unanswered in the assasination due to the following
1. Bullet which killed RFK did not match the bullet that came from Sirhans
2. The number of Bullets Sirhans had was 8 and all were accounted for but the cime scene totally had 11 bullets and the three bullets still remain a mystery
3. This suspects the possibility of more than one assasin but who was the other?
4. Who is the real killer , because it was conclusively proved the bullet that came from Sirhans wasnt the one which killed Robert kennedy
5. The shooting angle of Sirhans could have not created the fatal wounds on RFK back head and the most critical wound at the lower right left ear which caused his death.

Similarities in assasination
1. JFK and RFK both were videotaped on their killings
2. JFK and RFK both assasins where both arrested but another assasin hand was involved
3. JFK and RFK both assasins were not the real murderers eventhough they pulled the trigger
4. Their real assasins could still never be found.
