Just a thought but is there a chance Meyers and Holland and the so-called experts were just luring you in to make you look bad. It is so easy to rule this out as being factual that it is hard to believe anyone could fall for this absurd theory. Yet you and Corbett took it all in hook, line, and sinker.
You seem to think you are in the mainstream here. The reality is you are the outlier. You are a one-percenter. That's about how many people think there were only two shots. Far more people think there were more than 3 shots than think there were only 2. From the beginning, the earliest reports said 3 shots were fired at JFK's motorcade. That was the consensus of the people who were in Dealey Plaza. Specific witnesses, JBC, Bennett, Williams, Jarman, and Norman said there where 3 shots. The physical evidence indicates there were 3 shots. For some idiotic reason, you choose to believe Oswald started with an spent shell in the chamber even though there is no evidence of that, only your silly assumption.
