Lance, I believe I addressed the question you raise in my chapter 16 summary. Yes, I agree that it would make no sense from a Walker staged shot point of view, for Oswald to have been involved, unless there was anticipation or intent for Oswald himself, as the “Communist”, to be immediately publicly implicated and/or arrested for it. If that were not the expectation or anticipation, then i agree it doesn’t make sense. However the facts are Oswald was both involved and that did not happen, which calls for explanation.
So I am not actually disagreeing with your reasoning, only the unwarranted conclusion you draw (apparently, that the facts therefore aren’t true to begin with). The problem I attempted to address was why the expected, anticipated arrest and/implication of Oswald immediately in that shot did not happen. That is the puzzle that calls for explanation.
