No, the 45 degree angle bullet track through JBC is a fact. Dr Shaw never refuted it. He never mentioned it. Dr Shaw was part of the WC testimonies not the HSCA Panel. How could he refute any of their findings?
The description of the wounds and the medical analysis by the doctors are facts. Everything else is your pretend make-believe nonsense. Your made-up hypothetical crap does not mean anything to anybody. Is this Single Bullet Theory the lynchpin of your whole ridiculous conspiracy theory? Is that why you pretend
these opinions of yours have some kind of merit, and they are just unfounded opinions.
In looking over his right shoulder, JBC would naturally lean back a little and that would increase the downward angle of the bullet through his body. I would bet that Shaw's description was just an estimate. What are the chances it would actually be 45 degrees.
