Quoting McAdams only further damages your credibility. He is one of the biggest disinformation agents in the history of these forums. But I quickly perused the link you sent and it states this incredible bullshit:
"The campaign has been to push Kennedy's head wound to the very back of his head, in occipital bone, in order to promote the idea of a shooter from the Grassy Knoll."
That's just a prevarication. What do the earliest witnesses say? Clint Hill, the doctors, the nurses, and everyone who actually saw the head wound, say it was in the right rear of the head. Due to the obfuscation of Hoover and Johnson, folks like Tommy buy into the total nonsensical SBT theories. That's your right. It's mine to counter such assertions because I believe this case is very important.
Also, what you wrote about Hoover is totally irrelevant to this discussion.
