Max Holland is very good, especially at showing us, in the Robert Hughes film, the movement of something white (Oswald's t-shirt?) in the Sniper's Nest window about five seconds before the first shot rang out, that Oswald had to be standing and awkwardly leaning forward when he fired his steeply-downward-angled / missing-everything first shot (which we now know was at hypothetical "Z-124," i.e., half-a-second before Zapruder resumed filming at Z-133), that the ejection pattern of the three shells found on the Sniper's Nest floor support the scenario that Oswald was standing for his first shot and kneeling for his second and third shots, that overly ambitious, scandal-plagued and revengeful Jim Garrison changed his theory against Clay Shaw from "He organized a homosexual thrill-kill assassination of JFK" to "He organized the assassination for the CIA" due to a KGB article published in a Communist-owned Italian Newspaper three days after he'd arrested Shaw (which newspaper article -- or a clone of it that was published in a far-Left newspaper in France -- was given to him by JFKA conspiracy theorist Joan Mellen's husband), but I think he's mistaken when he postulates that Oswald's first shot glanced off the traffic signal's mast arm and indirectly nicked James Tague down by the triple underpass.
