This seems to studiously avoid the more Occam-like and evidence-based possibilities. In my humble and exceedingly uninformed opinion, both the "missed first shot" and any "frontal shot" are fantasies and red herrings. The plausible possibilities are (1) Oswald simply fired two shots and that's all there is to the JFKA, bada-boom bada-bing; or (2) Oswald fired two shots but the SBT is incorrect and a third shot that did not miss its mark was fired on a flatter trajectory from either the Dal-Tex or County Records building. I have no emotional attachment to either possibility, but I increasingly think #2 is far from implausible. (Orr has four shots, with a pro making the head shot and Oswald missing everything with his third shot immediately after that, so there are alternative possibilities within #2.)
The more I dive into the evidence and authorities supporting my views that folks like blowhard Dan O'Meara dismiss as "discredited nonsense," as I have done this morning in regard to the issue of when JFK sustained his throat wound , the more I discover that folks way more qualified than little old me do not regard them as discredited or nonsensical at all - quite the contrary. And the more I am convinced that way too often in JFKA discussions "theory" drives the "evidence" rather than the other way around - i.e., what folks want to believe occurred drives their interpretation of the evidence as to what did occur.
It would interesting to have the photographic, medical and ballistics evidence reviewed by a panel of world-class experts who have absolutely no dog in the fight - experts from Brazil and Sweden and China who care nothing about JFK or the JFKA and who haven't been influenced by 62 years of speculation.
