Absence of evidence is absence of evidence. Shaneyfelt testified as to which images he used: CE133A and B. If you want to argue that he used anything else, it's up to you to demonstrate that.
In the larger picture, you've claimed that "In all candor, Kirk had no friggin idea what Shaneyfelt looked at." Isn't it up to you to show that Kirk had 'no friggin idea'? And wouldn't Shaneyfelt's own testimony be evidence otherwise?
His method is to characterize any evidence that implicates Oswald in the assassination as "claims" or "speculation" and then it can be dismissed. He "deconstructs" accounts until they essentially disappear.
But he gets to make all sorts of speculation and "claims" and theories about evidence, about the motivations of people who identified Oswald or implicated him.
It's cheap and easy - we can do this with any event - and fundamentally disingenuous.
I noted above all of the fifty plus years of investigations, directly or indirectly, into the assassination and that concluded that Oswald alone killed JFK. Government investigations, news media investigations, investigative reporters, historians, biographers. This is the most studied event in US history.
His response to all of this was to label it "BS" and dismiss it. Even though he doesn't know what all of this revealed (neither do I; it's a lot of material: but I do know what they concluded). Whatever evidence is found will be dismissed by him. Simply by waving it off as "claims" or "speculation." Ballistics, forensics, fingerprints, photographic analysis, handwriting analysis, eyewitnesses, documents - whatever is present he will wave off.
