I had the impression that being anti-psychiatry (SSRI's, electro shocks) was common among Scientologists.

Louis Jolyon West
From Wikipedia, the free encyclopedia
Louis Jolyon ("Jolly") West (1924 in Brooklyn, New York - January 2, 1999 in Los Angeles) was an American psychiatrist, human rights activist and expert on brainwashing, mind control, torture, substance abuse, post traumatic stress disorder and violence.

While West was on his internship at the Payne Whitney Psychiatric Clinic he discussed with J.A. Winter the recently published book Dianetics and concluded that the "auditing" described in Hubbard's book used hypnosis. Winter made him known to L. Ron Hubbard once, but West's comment was: "Winter introduced West to Hubbard on one occasion but West said: "I guess I didn't find the man very memorable. I was more interested in the book which described the auditing technique in which they had preclears -- or prereleases if just beginners -- count backwards from seven to zero repeatedly until they went into a trance, although Hubbard denied it was hypnosis." West followed the activities of Scientology from that time on and has openly said and written that he thought the organization dangerous.

Social Control
In Hallucinations: Behavior, Experience, and Theory, West and Ronald K. Siegel explain how drug prohibition can be used for selective social control:“ The role of drugs in the exercise of political control is also coming under increasing discussion. Control can be through prohibition or supply. The total or even partial prohibition of drugs gives the government considerable leverage for other types of control. An example would be the selective application of drug laws… against selected components of the population such as members of certain minority groups or political organizations<5>
Conflict with Scientologists
According to West, the problems started after he published a textbook in 1980, in which he called Scientology a cult.<6>
On one APA panel on cults where every speaker had received a long letter threatening a lawsuit if Scientology would be mentioned, no one mentioned Scientology except West, who was the last speaker: "I read parts of the letter to the 1,000-plus psychiatrists and then told any Scientologists in the crowd to pay attention. I said I would like to advise my colleagues that I consider Scientology a cult and L. Ron Hubbard a quack and a fake. I wasn't about to let them intimidate me." (Psychiatric Times, 1991)
Scientology's Freedom Magazine interpreted anti-apartheid trips to South Africa as pro-apartheid (Psychiatric Times, 1991).

Others claim he was part of MK-Ultra and implicate him with people like Timothy McVeigh, but I have no proof of that.
Conducted by Dr Louis Jolyon "Jolly" West and two colleagues, the experiment took place in 1962 at the University of Oklahoma. West's stated intention was to see whether LSD - yet to hit the streets as a recreational drug - would induce a condition called musth in Tusko. Musth, which occurs naturally in all bull elephants, is a period of heightened testosterone production and high aggression. Why West should have been interested in this is unclear, though he has repeatedly been linked to the CIA's MK Ultra programme, which had been experimenting with LSD on unwitting subjects like Tusko since 1953.

A lot of people on the (CT/inside job) side claim that terrorists are patsies and mentally ill people can be easily manipulated, examples would be Zacharias Moussaoui.
Another view could be of course that terrorist are just mentally ill, because no rational person would become one.
