The WC apologists' posts in this thread are a sad but telling example of why nearly all the progress made on the case has been made by WC skeptics. WC apologists are chained down by the Commission's fictional one-shooter-three-shot scenario and so they are forced to come up with ludicrous explanations for evidence that deep down they know refutes the single-bullet theory.
Of all the whacky, self-evidently bogus arguments put forward by WC defenders, the claim that JFK and Connally were hit by the same bullet in Z224 has to rank in the Top 10.
Anyone with functioning eyes can see that JFK is clearly and obviously already reacting to a wound when he partially reemerges into view in Z224 as we see his left forearm nearing the level of his throat, and Jackie is clearly and obviously already noticing JFK's reaction in Z224. Unless you're committed to denying your own eyes can see, you know that these reactions must have started many frames before Z224.
Moreover, even if you force yourself to ignore the self-evident reactions in Z224, there is also the fact that in Z225, when we can see both of JFK's forearms, we see that JFK has both of his hands in a clutching formation and is bringing both hands up to the level of his throat. There is no way he could have done this in response to a shot at Z224. Humans cannot respond and move their arms that rapidly after being wounded. Not on this planet.
And then, of course, there is the fact that Connally survived his wounds and adamantly insisted he was not hit before Z228. No one knows you better than you. No one knows what your facial expressions and body movements mean better than you do. Connally had knowledge that no one else had (1) because he was the guy who actually experienced the wounding, and (2) because no one knew him better than he did.
After carefully studying high-quality prints of the Zapruder film under high magnification, Connally said he was certain beyond all doubt that he was not hit before Z228, and he identified Z234 as the moment of impact--and just four frames later, or just 4/18ths of a second later, or just 222 milliseconds later, or less than 1/4th of a second later, we see the start of the dramatic slamming down of his right shoulder, in perfect harmony with his statement that the bullet's impact felt like someone hit him hard in the back.
I know we can all see these things. It's just a question of whether or not one is willing to be honest and credible about what they prove.
