A post on Fred Litwin’s site quotes an article by Josiah Thompson that the 12:40 PM photo (time stamped by the Hertz clock atop the TSBD in the background) that shows a blonde man ostensibly pocketing a bullet with Buddy Walther’s looking on really shows Luke Mooney and that it was Sheriff Bill Decker rather than Walthers. I am skeptical about Decker’s plausibility of being in Dealey Plaza at that time since he was in the lead car with Curry which went with the motorcade to Parkland. So whether Thompson was correct about Mooney is also in doubt. By that time, Mooney supposedly had already searched the railroad yard having run there from the County Sheriff’s office on Main snd Houston after the shots were fired. Seems unlikely.
