Arab ones, like.

Probably, but it doesn't sound like it was too effective, besides getting the patsy there with a gun and then having them not remember too much. Others actually had to do the effective work of the killing etc. As far as the pilots. I'm sure they'd try anything on them, but it was probably more simple to use remote control technology. That seems to make the most sense to me anyway.

From your wiki link I found this interestng:

"MK-ULTRA, perhaps predictably, plays a part in many conspiracy theories given its nature and the destruction of most records. Some claim the MK-ULTRA project was linked with the assassination of Robert F. Kennedy. They have argued that there is evidence that the assassin, Sirhan Sirhan, had been subjected to mind control, though such ideas are generally dismissed due to a lack of supporting evidence. Recently, these views have become more widespread after the evidence cited by Sirhan's most recent lawyer Lawrence Teeter, in the June 11, 2003 Interview with Sirhan's attorney Lawrence Teeter on KPFA 94.1 / Guns & Butter show"

The 2003 Lawrence Teeter interview confirms Hypno-Programming and gives misconduct details related to the Trail (audio):

Still, this stuff is close to science fiction. I guesse Truth is stranger than fiction.

In William Pepper's book, there is testimony that ties Raul, Ray's handler, with Jack Ruby in Dallas.
