This is not an argument just against the SBT. It is an argument that the bullet did not transit JFK's neck. That appears to be at odds with all the evidence.

Your argument about the trajectory not going from JFK's throat to JBC's right armpit is reasonable one that has evidentiary support. But not the suggestion that a bullet did not transit JFK's neck.
The idea that a bullet transited JFK's neck is at odds with all of the best evidence that we now have:
-- The ARRB disclosures about the absolute, complete, final determination during the autopsy that the back wound had no exit point.
-- The fact that the shirt slits were made by the nurses.
-- The fact that JFK's tie had no hole in it, only a small nick near the left edge of the knot.
-- The fact that the shirt slits had no metallic traces around them, had no fabric missing from them, and were below the inside collar band. The photographic evidence makes it clear that JFK's tie knot was neatly centered between the collar band, which proves that no bullet could have exited the slits and then created a nick near the left edge on the surface of the tie knot.
-- The fact that there was no path from the back wound to the throat wound without smashing through the spine--not just nicking the edge of C7 or T1 but smashing through the middle part of the spine, as Dr. Mantik established with an overhead CT scan of an adult male with the same height and width as JFK.
-- The fact that the throat wound was only 3-5 mm in diameter, neat, and punched-in.
-- The fact that the damage that the Parkland doctors observed under/behind the throat wound clearly indicated the bullet ranged downward into his chest.
-- The hard physical evidence of the rear clothing holes in JFK's coat and shirt, which prove the back wound was too low on the back to have exited the throat, even if we did not already know that on the night of the autopsy, the pathologists absolutely, positively, and completely determined that the back wound had no exit point.
