I wouldn't stoop to reply, but this is CLASSIC of what MTG does. Reality simply cannot penetrate the CT bubble in which he lives.
I'd bet good money you haven't even read O'Toole's book, and thus you don't know that he presents an extensive discussion on studies on the reliability of VSA (aka PSE) polygraphs. Dr. David Scheim, who holds a doctorate in mathematics from MIT, has said the following about VSA/PSE polygraphs:
. . . the Psychological Stress Evaluator (PSE), a lie-detector device that measures stress by voice pattern analysis. Demonstrated reliable in several tests, it is used by hundreds of U.S. law enforcement agencies and accepted as evidence i more than a dozen states. (Contract on America, 1988, p. 160)
The ABSOLUTELY SCATHING review of O'Toole's book that I cited and quoted from was from the PROFESSIONAL JOURNAL OF THE AMERICAN POLYGRAPH ASSOCIATION. Hello?
Forty years later, Sean DeGrilla and his highly professional VSA cohorts ABSOLUTELY SHREDDED O'Toole's work and demonstrated the gross error that he had either incompetently or fraudulently committed.
The issue is not the accuracy of VSA. The issue is the incompetence and lack of ethics of O'Toole. Correctly done VSA by DeGrilla and peer-reviewed by world-class VSA experts showed Oswald as LYING.
Finally, a word about George O'Toole himself. As usual, since O'Toole reached the conclusion that JFK was killed by a conspiracy, Lance Payette seeks to minimize his qualifications, describing him as "a CIA computer specialist." Actually, he was a bit more than a computer specialist, although that in itself is a valid, relevant qualification. O'Toole served as the chief of the CIA's Problem Analysis Branch.
No, he was not the chief of anything during his less than three years with the CIA. His PRECISE POSITIONS that I quoted were from a CIA DOCUMENT describing his employment. This was not a document attempting to minimize O'Toole or his CT views. It was simply a document briefly describing each of the principals of the Committee to Investigate Assassinations:
https://www.cia.gov/readingroom/docs/THE%20COMMITTEE%20TO%20INVESTIG%5B16506075%5D.pdf.
I repeat: "He was employed as a Digital Computer Systems Analyst in March 1966. He resigned 24 January 1969 from a position as a Research Officer, GS-14, ORD/DDS&T" (Office of Research and Development, Directorate of Science and Technology).
He was not an "ex-CIA agent." He was not a "bureau chief." He was not "Chief of the Problem Analysis Branch." These are all titles that O'Toole either misappropriated or allowed to be attached to his name because what he actually was didn't sound sufficiently impressive. You will also see him referred to as a "case officer."
If this isn't sufficient for you, there WAS NO "Problem Analysis Branch" in the Office of Research and Development. It was called the Analysis Division.
https://nsarchive2.gwu.edu/NSAEBB/NSAEBB54/st33.pdf. A history of the Analysis Division written in the 1970s said the Chief (name redacted) was appointed in 1968 and remained Chief "throughout its history" to the date of writing.

This is what MTG does, again and again. His crap is exposed, reamed, steamed and drycleaned - AND HE FLAT DOESN'T CARE. In the SAME THREAD in which it's been exposed, he repeats it all over again! There is something seriously wrong with this guy.
