There is not a "shred" of evidence he was on the 6th floor? LOL. Round and round we go down the rabbit hole. Let's see. Just his rifle, fired bullet casings from that rifle, his prints on the SN boxes by that window. a long bag with his prints next to the 6th floor window from which the shots were fired. Oswald apparently couldn't get to the SN and remain unseen and escape the floor without having "superpowers" while some other person could. Laughable. Weak defense attorney nonsense to defend a guilty client.
Impasse - a situation in which no progress is possible.
IF the rifle was his.... How does that prove that Lee was there at 12:30 that day?
Fired bullet casings from the rifle....How do they prove that Lee was there at 12:30 that day ? Those spent shells could have been fired days or weeks before 11/22/63. And who knows who fired them.
His prints on boxes?.... REALLY Mr "Smith". How utterly STUPID of you to try to use those prints as proof of anything other than proof that Lee Oswald worked at the TSBD and he handled boxes.
And a paper bag that has no chain of evidence ..... ROTFLMAO!
