The same old tired “Richard” game of calling speculation “evidence” and making claims about the evidence that just aren’t true.
Marina didn’t “confirm he kept his rifle there”. There’s no evidence that they were “his bullet casings”. No evidence that the rifle allegedly found in the sixth floor was Oswald’s rifle or was ever in the Paine garage. No evidence that the “long bag” was on the sixth floor when the so-called “sniper’s nest” was discovered or that this was the same bag Frazier saw Oswald carrying, or that it ever had a rifle in it. Add up a whole bunch of speculation and you wind up with nothing more than speculation.
