You seem to be of the opinion there are multiple truths and it is a multiple-choice exercise. There is only one truth of the JFKA and all other theories are simply false. Oswald was the assassin and he carried out the assassination in only one way. Once that way is determined, it is pointless to consider there are alternatives. Your scenario is simply bonkers and undeserving of serious consideration.
Tom Graves and I are in agreement that there was an early missed shot but we have a sharp disagreement as to how early that shot occurred. Since there are only clues and not definitive proof of when the first shot occurred, I can recognize that there is a possibility that he could be right and I could be wrong. I can't give your scenario that same consideration. There is no possible way you could be right
Both you and Tom think the other is wrong. I am just saying you are both right - on the other being wrong.
