Sorry, late tagging. It's been bugging me.
Wracking my brains re more than one shooter, going back through bookmarks, notes etc.
So, pages 260-272 of The Man Who Killed Kennedy, the case against LBJ give a forensic and witness based overview of shots, directions and ballistics with cross references and sources, all verifiable.
Also G Paul Chambers; Headshot: The Science Behind the Kennedy Assassination deep dives, with scientific based conclusion.
3 Shots, 100% confirmed, 4th is with 99% certainty, up to 6, some degree of scepticism but acoustics etc are difficult due to reproduction and the reliability of the Dictatape from the motorcycle, however reproduction did take place with ballistics experts and with a 95% degree of certainty showed a "rifle shot" from the Grassy Knoll.
In my mind and with further statements that have come to light and the "pressure" that was applied at the time by 3 letter agencies and then subsequent retraction, there should be no doubt that more than 1 shooter was active on that day and that while Oswald may or may not have been one of them, he did not deliver the "kill-shot"
