Creative Speculation

"Wm Seger", your colored arrows do little but presume correspondence where none exists.

"Speer is wrong that the measurement was from the bottom of the mastoid process rather than the "bottom tip."

There is no difference between the two.

"it's "obvious" to Speer that we should simply ignore what the photos clearly show"

The photos, as you presented in your deceptive diagram, show nothing because there is no relationship or correspondence between them. Faced with the collapse of your theory, you decide to attack the messenger, as you sought to diminish Fiester, Dolce, Shaw, etc. - and in all of those cases the crux of your argument is that the above are simply wrong.

"you're still trying to protect your "back-and-to-the-left" delusions by being willfully blind to the forward head-snap and its clear meaning. "

"I just gave you three different ways your conclusion could be false, and the only response you could come up with is that you don't think those are possible…"

different way #1 - "perhaps they were making too much noise themselves". The layout of the staircase at the TSBD makes this extremely unlikely (as can be seen in photographs presented in the video). If the fleeing man was ahead of them, he would have been heard as they approached the stairs. If he was behind them he would have been heard as they moved to the next set of stairs on the third or second floor. The Warren Commission had the opportunity to time the movements of Adams and Styles, and help establish a clearer picture, but they refused to do so.

different way #2 - "perhaps it just didn't register because of the situation so they don't recall it" so both of them, independently, suffered some sort of amnesia or sensory deprivation, even as their descriptions of what they did and when they did it were clear, precise, and consistent. Can I point out here that you frequently resort to lectures on "logic" and yet…

different way #3 - "perhaps the timing you would like to use is not all that accurate…" The timing is not mine, it is the clear and consistent recollections of three witnesses. The Warren Commission, through David Belin, recognized the need to "pin down" the timing, but, in the end, they did not do so. They refused to test this timing, even as they did so in every other situation. They refused to even talk to one of the three witnesses (and inferred in the Report that Adams went down the stairs alone). Belin attacked Adams' integrity by inference and coached testimony, and when Garner's statement confirmed in every way that Adams and Styles were on the stairs exactly when the official story needed Oswald to be there, Garner's statement was ignored and hidden from public view until 1998.

It's pretty obvious what relationship the Adams story has to "valid logical inference", even if it is lost on yourself.
