Dr. Aguilar & Josiah Thompson: It wasn't a Jacketed Bullet, It was a Hunting Round

"A snowstorm of lead can't come from a jacketed bullet." (Thompson)
Which means, on top of all the other reasons, that it wasn't shot from the planted Carcano.
There's also confirmation here that the Kennedy family is restricting access to the X-Rays, & they let Aguilar see them. Aguilar has disputed Horne over the medical evidence, over what Horne terms a "major blind spot," so, and I'm just thinking out loud here--which is what all these notes in the description are--I consider that to be a possible factor in Aguilar's blind spot, that he may need to alter his version to maintain access to the X-Rays. Haven't looked into it, don't know, but that is a possible explanation, because Aguilar appears to be honest and competent, and he says Horne hasn't provided extraordinary evidence, which is clearly not true.
