The second is about Charles Whitman (thanks for reminding me of his name but your info is incorrect and a "friend's" testimony, if there ever was one, is unreliable and therefore unscientific to assume it is true). And no, the case is most certainly not a "scientific hoax." (Where did you hear that?)
"Post-mortem autopsy of his brain revealed a glioblastoma multiforme tumor the size of a walnut, erupting from beneath the thalamus, impacting the hypothalamus, extending into the temporal lobe and compressing the amygdaloid nucleus (Charles J. Whitman Catastrophe, Medical Aspects. Report to Governor, 9/8/66)."
My info is correct Summerland. Their was only one autopsy performed on Whitman. Here's a link to it http://www.autopsyfiles.org/reports/Other/whitman,%20charles_report.pdf
Here's an exact quote from it “ In the middle part of the brain, above the red nucleus, in the white matter below the gray center thalamus, is a fairly well outlined tumor about 2x1 .5x1 cm in dimensions, grayish-yellow, with peripheral areas of red as blood.” - Dr. Coloman de Chenar.
Here's an actual quote from the press release of Governor Connelly's commission investigating the cause of Whitman's running amuck
“ 4. Glioblastoma multiforme (sections of two pieces of tumor reportedly removed from the right temporo-occipital white matter by Dr. de Chenar on August 2, 1968)....
7. Multiple wounds of the body.
The malignant tumor removed from the brain by Dr. [Coloman] de Chenar microscopically exhibited the features of a glioblastoma multiforme with a remarkable vascular malformation. It contained widespread areas of necrosis with palisading of cells characteristic of glioblastoma multiforme.
No evidence of other disease or previous trauma was observed although the destruction of the brain by gunshot wounds was so extensive that anatomic relationships could not be completely evaluated and the examination of all the major nerve tracks and nuclei of the brain was impossible.” - Press Conference, Medical Aspects, Charles J. Whitman Catastrophe, page 7

The friend's eyewitness testimony was recorded in a report by the FBI that was classified, but partially out under the freedom of information act request. It had vials of dexedrine on him when he was killed, which further confirms "the eating them like popcorn" quote. He was taking dexedrine and valium at the same time under prescriptions.

Incidentally it was the psychiatrist whom reported that he was a young muscular man seething with anger and talking about wanting to kill people by shooting them from the university of Texas at Austin tower whom put him on dexedrine! I'll go out on a limb and speculate that the FBI both had a report on Whitman and classified it because he was an early test subject of the CIA's MKUltra program. Whether that is correct or not, he certainly was a victim of psychiatric malpractice and is part of a long list of people victimized by trying to cure people with drugs.

Governor Connelly rejecting the autopsy report and seeking proof that 'Whitman's brain tumor did it' and the use of Whitman as evidence that a defective brain caused his behavior were the hoaxes involved. There's no evident that "pressure on the amygdala" causes anything. The idea is completely "unscientific" The hoaxers are taking an hypothesis as a fact and then trying to gather evidence for it - the very essence of being unscientific.
