Zapruder is sitting in a chair and Watson is talking and from that you know everything he has heard after entering into the building and standing then sitting in the studio? Did you miss the part where Watson could not wait to tell him there were three shots. Did you also imagine hearing Zapruder mention a shot halfway between the throat shot and the head shot?
You need to watch the whole continuous feed for the hour or so beforehand. Watson is on the air continuously. Your allegation was that he caused Zapruder’s confusion. But we can see that Watson did not say anything to him in the hour prior to beginning the interview. He did not mention 3 shots until after Zapruder said:
“And as I was shooting—as the President was coming down from Houston Street making his turn; it was about a half-way down there—I heard a shot, and he slumped to the side, like this. Then I heard another shot or two—I couldn't say [whether] it was one or two—and I saw his head practically open up [places fingers of right hand to right side of head in a narrow cone, over his right ear], all blood and everything, and I kept on shooting.”
JBC, Nellie, and Jackie all mention the first shot hit JBC. Are you still struggling with the basics?
I am struggling with that. But it is because I am struggling to understand what universe you are in.
