This should clear things up

Yesterday i satisfied myself that................................
(1) Tague was hit directly by a fragment that went under the rollbar & tween the vizors & over the windshield. The only question being whether that line passes throo Tague's left cheek (which i think it does).[edit][tague was hit by a fragment of a slug from one of 3 or 4 shots fired by Hickey].
(2) The mainly copper fragments found in the limo CE567 & CE569 made the dent & the cracks & were both from Hickey's AR15. [edit][the dent was made by a whole slug from one of 3 or 4 shots fired by Hickey].
(3) The fragments-shrapnel that hit JFK from Oswald's first shot (of his two shots) & ricocheted off the collar-rods-pipe of the signal arm (a) hit JFK on the back of his head & (b) are in the X-rays (up to then i thort that it had been CE567 or CE569 that glanced JFK's head).
(4) There was no missing bullet or missing fragment from Hickey's shot, except of course for the fragments-shrapnel-dust that must have been in the missing bit of brain & the bits that landed outside the limo (including what hit Tague). [edit][Hickey fired 3 or 4 shots][some lead fragments in the limo might have been from these shots][otherwise we dont know of any other fragments or the 3 or 4 empty casings].
(5) And i answered your query in #14. I reckoned that the Bronson freeze frame is too early -- Hickey had 10 frames to stand up a little & shoot JFK in Z312-313.
(6) And today i can add that the drawing in your linked article is silly. It shows Hickey having to stand up with the AR15 under his left armpit. It could easily have drawn him sitting & holding the AR15 on top of his head. Nope, Hickey didnt have to take very long to stand upish, bearing in mind that he was half standing already by sitting on top of some cases placed for some reason on the seat. And in QM the 2 vizors are a mile apart, plenty of space for the shot without having to go up over the large vizors. [edit][i debunked the debunking in another thread].
Yes yesterday was a good day, like all of the others, & i am not sure what to look into today, there is the question of what was Oswald's plan, eg a safe house, or pull a robbery for cash & get to Mexico & then Cuba. But Dealey Plaza has almost zero mystery to me now.
