And what exactly would that conjecture and innuendo be?
That the above is evidence of anyone knowingly and intentionally blaming/framing LHO as a patsy.
How is it conjecture that initials that were supposed to be on the shells but aren't? It's factual and it requires an explanation.
How is it conjecture to question an index card that shows up a week after the event, with an alleged print from Oswald taken from the rifle, when the FBI failed to find any prints on the rifle earlier? There are only two possible explanations; either Day screwed up big time or the print was added to the record after the fact.
And John said "Just to name a few". There are a whole lot more issues with evidence which one needs to overlook in order not to see the possibility of a frame up.
Now before you jump to conclusions; I am not saying Oswald was framed. I am saying that they needed to resolve the case as quickly as they could and Oswald's death provided them with the possibility to do so regardless of whether he really did it or not.
