Jerry, Am I mistaken here... Is this not from the Clark Panel finding referenced in your post above?



That's a drawing produced by the HSCA, showing their general acceptance of the Clark Panel's siting of the skull entry wound ("inshoot"). The "outshoot" on that drawing did not come from the Clark Panel. The Clark Panel Report ("Panel Review", 1968) is here: Link.

The Bethesda pathologists reviewed the autopsy materials earlier, submitting a report (nicknamed "Military Review", 1967): Link.

I disregard the HSCA "outshoot" site. But if you're going to use the HSCA "inshoot/outshoot" slope line to back-project a trajectory, at least consider a cone projection backwards to represent the margin of error and potential for deflection.


 
Above: Example of back-project method. Note it doesn't show the head-wound case.

Don't back-project using a singular line.


HSCA Exhibit F-139

Using a back-projection cone that they said represented a reasonable margin of error, the HSCA discover that the rear portion of the projection cone included the Oswald window. They never claimed a singular-line would trace from the outshoot backwards through the inshoot and further backwards on into the Oswald window.

If one uses the Humes/Studivan "near EOP" inshoot, there is a degree of deflection necessary to account for the entry site to redirect to the gaping exit wound site. There is also a theory that the explosive head wound in Z313 is not really an exit wound at all, but the entry wound for a frangible bullet.

The deception here is:.....  Labeling the SE corner window as "The Oswald Window"....   Lee was in the Domino Room at the time of the murder....

And although a "projection one may include that SE corner window that "projection cone" is deceptive because even though the window is in that area...it does NOT mean a rifle could have been fired from several feet back from that window by a sniper sitting on a box and using a stack of books as a steady rest for the rifle. ( as the theory proposed by the authorities suggested) because the muzzle of the rifle could not have been declined to hit anything on Elm street...

Window opened more on day of assassination than how it is now at the Sixth Floor Museum
Box Arrangement as seen inside
 
Same Box Arrangement as seen outside
Seems enough room to position a rifle over the topmost box and acquire a target.

In the first place you're not using the photos....you are using a phony drawing...and secondly....the authorities theorized that the arch villain Lee Harrrrvey Osssswald sat on a box back away from the window and used the stack of three rolling readers as a steady-rest for firing the rifle......using their theory....It would have been impossible to decline the muzzle of the rifle down onto the murder scene.....
