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.
There is not a "shred" of evidence he was on the 6th floor? LOL. You can laugh all you want, but you are actually laughing at your own stupidity.
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. Just his rifle,Lol. Even if it was his rifle, how does that prove he was on the 6th floor at 12:30 on 11/22? Answer: it doesn't
fired bullet casings from that rifleLol. When were the bullets belonging to those casings fired? And how does that prove he was on the 6th floor at 12:30 on 11/22? Answer: it doesn't
his prints on the SN boxes by that windowLol. He worked in the building and part of his job was to move boxes. And how does that prove he was on the 6th floor at 12:30 on 11/22? Answer: it doesn't
a long bag with his prints next to the 6th floor window from which the shots were fired. What bag? The one that can not be seen in any in situ photographs? And how does that prove he was on the 6th floor at 12:30 on 11/22? Answer: it doesn't
See the pattern?
Oswald apparently couldn't get to the SN and remain unseen and escape the floor without having "superpowers" while some other person could. Only if you assume that shots were actually fired from the 6th floor window. We only have Brennan's word for that and he lied about just about everything from his location to the identification, on second thought, of Oswald. Not the most reliable witness.
All you really have is a theory based on all sorts of assumptions. The fact that those assumptions are highly questionable and are partly a physical impossibility, except of course in a fairytale, doesn't make any difference for you. It's one thing to believe that Oswald was the lone nut gun man but to do so without actual conclusive evidence is absolutely pathetic. As I said before, you haven't got a shred of evidence that Oswald was actually on the 6th floor of the TSBD at 12:30 on 11/22/63.
