The amount of evidence demonstrating that the first shot passed through both men at z222/z223 is ridiculous. Anyone who genuinely accepts the weight of evidence can come to no other conclusion.
Yes, there is ample evidence that a bullet passed through those men at that time frame but there is also ample evidence that there was a shot before that. JBC insisted until his dying day that it was the second shot that hit him. He heard a shot before the one that hit him. Glenn Bennett also heard a shot before seeing the second shot strike JFK. We can see JBC turn to look over his right shoulder at Z164 which he said was his reaction upon hearing the first shot. Are we supposed to believe that both JBC and Bennett imagined hearing a shot before the shot that struck JFK and JBC, because that is what is required to believe the first shot was the single bullet. I can understand how you could be unconvinced of a first shot miss but I don't know how you can be so certain there wasn't a missed first shot. I think there is strong evidence the first shot was fired about Z147 but I wouldn't go so far as to declare that a certainty because the evidence is less than definitive. It seems completely illogical to me that you could rule out even the possibility of a missed first shot.
Once accepted there is little choice but to have the headshot as the second shot followed by a third, missed shot.
I don't know how anyone can say there was positively a missed third shot when there is practically no evidence of that and there is very strong evidence that the first shot missed. Tell us why you think a missed third shot is more likely than a missed first shot. What are you seeing that the rest of us can't?
In reality, the first shot was a miss in that the target was the head and the shot missed low, passing through JFK's neck. Luckily for the shooter JFK stayed in an upright position as he took his time to line up the fatal headshot.
How can you know what Oswald was aiming at. As a Marine, he would have been trained to shoot at center of mass. That doesn't prove he was aiming his first shot and JFK's torso, but it is certainly a possibility. How can you be so sure the back shot wasn't his aiming point and the headshot struck high? You seem to want to arbitrarily dismiss possibilities except the ones to your liking.
I assume the shooter had already decided he was going to take a third shot, which is why it followed so closely behind the second shot, but why did it miss so wildly?
I suspect the shooter pulled the shot high due to the sudden arrival of Clint Hill on the back of the limo.
Your suspicions aren't evidence of anything, nor are your assumptions, but you seem to lean heavily upon them to establish your beliefs. It seems odd to me that Oswald would have even taken that shot once JFK fell over to his left which he did as soon as Jackie had climbed out onto the trunk, which she did just as Clint Hill was grabbing the handhold.
