I documented in a previous reply that Boswell told journalist Richard Levine in an extensive interview in November 1966 that at the time of the autopsy the pathologists had already been told "what had been done by the physicians in Dallas," in addition to the "probable extent of the injuries" ("Pathologist Who Made Examination Defends Commission's Version," Baltimore Sun, November 25, 1966, p. 3; see also Harold Weisberg, Post Mortem, Skyhorse Publishing, 2007, reprint of 1975 edition, p. 37; and Weisberg, Never Again, Skyhorse Publishing, 2007, reprint of 1995 edition, p. 217).

I should add that Boswell also revealed the additional crucial information that Humes's phone conversations with the Dallas doctors the next day, 11/23/1963, "confirmed what was already a certainty to the pathologists -- that there was a bullet wound in the President's neck at the point of the tracheotomy incision" (Ibid., p. 4; see also Weisberg, Post Mortem, p. 37).

The official lie that emerged soon after the autopsy was that the autopsy doctors had no idea there was a throat wound until the day after the autopsy. Historian William Manchester was the first to expose this falsehood in his 1967 book The Death of a President, but his discovery was ignored by the major news outlets. Even most WC critics failed to take advantage of Manchester's discovery because they viewed Manchester as a tool of the Establishment, as a sort of "court historian," and thus didn't bother to read his book.

Dr. John Ebersole, the autopsy radiologist, was the next person to expose the official tale when he was interviewed by the HSCA in March 1978, as I also documented in a previous reply. Among other key disclosures, Ebersole informed the HSCA that Humes spoke with the Dallas doctors by no later 10:30 during the autopsy. This was at least half an hour before the end of the exam phase of the autopsy, and at least two hours before the end of the consultation phase of the autopsy.

Ebersole also revealed that "further probing" determined that "the distance traveled by this missile [the back-wound bullet] was a short distance inasmuch as the end of the opening could be felt with the finger." This is one of several disclosures that confirm what we learned with the release of the transcript of the WC's 1/27/1964 executive session, namely, that the first two drafts of the autopsy report said nothing about the throat wound being an exit point for the back wound and that, not surprisingly, the back wound had no exit point. Mind you, this was late January 1964, and the transcript shows that Rankin was referring to documents from the autopsy.

As I also documented in a previous reply, military aide Richard Lipsey witnessed the consultation phase of the autopsy and reported to the HSCA that the pathologists were certain the back wound had no exit point. Crucially, Lipsey added that the doctors concluded that the rear-headshot bullet had exited the throat. This is a revealing datum because we know from the 1/27/1964 WC executive session transcript that one of the first drafts of the autopsy report said a fragment from the headshot exited the throat, that the throat wound was the exit point for a headshot fragment. This is also further proof that the pathologists knew about the throat wound during the autopsy.     

That's funny coming from the most incompetent poster on this forum.
So you think JBC made up that part about looking over his shoulder after hearing the first shot.
That is exactly what JBC said he did in response to the first shot. Had it not been for his testimony, I would not just assumed he turned in response to the shot. You have to put 2 and 2 together to figure this part out. Apparently, that's beyond your mental capacity.
I guess your lack of critical thinking skills prevents you from figuring out that it is difficult for a large man in a small seat to turn his body. 
JBC told us in no uncertain terms that he turned to look over his right shoulder in reaction to hearing the gunshot. He also told us that unable to see JFK, he had started to turn back toward the front when he felt the second shot hit him in the back. That would have been about the same instant he reemerged from behind the sign.

So what is the stimulus that JBC is responding to if not a gun shot?
We see JBC turning to look to his right between z160 and z169. Within less than two seconds all four occupants of the back of the limo all turn to face their right, looking in the direction of the crowds lining Elm Street. All four occupants appear to be responding to the same stimulus, JFK begins to smile and wave at the people on his right (a very strange reaction to hearing a gunshot!)

None of the other passengers recognized the first shot for what it was. JBC was an experienced hunter and knew the sound of a rifle when he heard it. As he later said, he immediately thought it was an assassination attempt. That was confirmed about 5 seconds after the second shot hit him when he was showered with pieces of JFK's brain.
You make the same mistake many people make. You assume every witness has accurately remembered the event which can't possibly be true, since there are multiple versions of what happened but the JFKA only happened one way. Witness statements should be believed if they can be corroborated. JBC's account is corroborated. He said he turned to the right in reaction to hearing the first shot and we see him do that beginning at Z164. We can interpret the conflicting witness accounts in one of two ways, either some of the people on Elm St. didn't recognize the first shot for what it was or JBC reacted to a gunshot that didn't happen. Since you are really, really bad at weighing evidence, it's not surprising that you chose the wrong one.
Typical FUBAR analysis from you.

You initially posted this:

"Your explanation ignores the fact the Z-film shows JBC began looking over his right shoulder at Z164"

Your assertion was that the Z-film showed JBC attempting to look "over his right shoulder", just as he'd testified he'd done.
I proved, using the same footage, that you are totally F0S and that JBC merely turned to his right in the Z-film and was NOT attempting to look over his right shoulder, as you had so ignorantly claimed.
But during the insane rant of your last post I couldn't help but notice a slight change in your claim:

"JBC's account is corroborated. He said he turned to the right in reaction to hearing the first shot and we see him do that beginning at Z164."


So, now he's not trying to look over his right shoulder, as you so stupidly claimed, he is now just turning to the right - exactly as I had argued!!
You have changed your argument to my argument and still think you are in the right 

I don't think I've ever seen anything so devious or cowardly attempted on this forum.
But that's no great surprise coming from someone as ignorant as yourself regarding anything about this case outside what you've swallowed down from the Warren Commission.
Stay in your lane.
Every single time you try to debate you end up looking like a buffoon.

Oh really?  Got ‘hanging chad’ ? lol

Send him to Kushner’s pal Salami man in Saudi Arabia, they’ll live-stream it, like all their other beheadings.  Hey, Trump outsources humans to many countries now.  They’re their problem now, ese.

Mark, compared to most members here, i think i've been living under a JFKA rock 

well I suggest one day reading the warren commission report.  there’s lots of images there!
