That's a pretty polite response from Canning considering you accused him of "using faulty reasoning" and having Connallly sitting over the centre console.
I never accused him of "faulty reasoning" when he was alive. Unfortunately, he died in 2009. The "faulty reasoning" that I alleged here could be seen as sound reasoning based on a "faulty premise" (that JBC's right shoulder would have been visible in Betzner's photo if the man in front of Betzner had not been there). Mr. Canning seemed to acknowledge that the premise was not correct ie. it was "faulty".
As a result, one would have to conclude that JBC's head was possibly 8 inches closer to the middle of his seat than where Mr. Canning had placed him. That would put him in the middle of his seat. Canning was, nevertheless, not persuaded that the path would have missed his back on the left side. He did not appear to consider how JBC being turned toward the right as seen in the zfilm at z193-200 could affect that. The bottom line is that if Canning's placement persuaded the HSCA that the trajectory could have intersected Connally's right armpit, moving him even 3 inches farther right let alone 6-8 inches, would have called into question such a conclusion.
Canning agrees with me that Connally's head (if it were not as inboard relative to Kennedy as he determined) would be visible in Bretzner.
It is rather obvious to all of us that his head would be visible if the man in front of Betzner was not there. He never said that would mean Connally
was as inboard he had placed him on his assumption that his entire right shoulder was blocked. That should be obvious to all of us as well. Canning said " The resulting shift would not destroy the conclusion I drew." Of course, it doesn't. The failure of the presumption alone just means that we cannot place a rightward limit on the position of the right shoulder - just the rightward position of JBC's head.
I have done a Bretzner sightline in SketchUp and Connally's head is just barely blocked by the foreground figure. If Connally were a little bit less inboard relative to Kennedy, a portion of his head would be visible.
I would like to see your analysis and drawing. You have to take into account that by being turned to the right as JBC's torso is in z186, his head has to move forward away from the seat back, to accommodate the turned torso.
Seems he's cautioning you on your "simultaneous eye-witness evidence" with a personal antidote.
I think you meant "anecdote". He candidly admitted "Your explanation of the power of simultaneous eye-witness evidence impressed me particularly in view of my recently recognized poor performance in a stressful situation involving "freeway rage". His anecdote was simply that he was not a very good witness in the incident he described - not that 40+ people observing the same shot pattern were bad witnesses. If that were the case, they would only have a random chance of agreeing with each other. I think Canning understood probability and statistics.
That only shows the front half of the 5th rib, genius. The 5th rib slants down from the back area. A bullet entering the HSCA inshoot and going downward and to the left would contact it pretty quickly. And without the Dali-esque deflection required by your theory.
So Dr. Shaw misplaced and misidentified the location of the entry wound? The axilla or armpit is the region immediately below the joint between the torso and the arm. The fifth rib is below that joint even in the back:
Gee, Andrew, you have a couple of years experience in SketchUp and 3D on me. Don't expect me to obtain overnight your mastery of fine precision and vivid reality.
So you must be agreeing that you have not invalidated anything. Still waiting for your less than precise, not vividly real views.
