It isn't that the evidence of Oswald's ownership of the rifle is deficient or lacking in any respect. How could there even be any more evidence of such under the known circumstances? But no amount of evidence can ever convince a CTer. They effectively have adopted an impossible standard of proof on the topic which they then attempt to pawn off as doubt. No legitimate historian has expressed any doubt whatsoever regarding Oswald's ownership of the rifle.
Over and over we go, and you just pretend there is not a giant hole in your story, you have zero evidence he received the rifle! That is just a regular standard of proof don't you think?
What defines a legitimate historian?
Don't get me wrong, you are of course quite correct that the experts in the eye of the mainstream do tow the line So just keep looking to those who are paid to give their opinions instead of independent researchers
