BuellWesleyFrazier did not see, would not have seen, and could not have seen LeeHarveyOswald on the TSBD Entrance stairs/landing during the filming at or near the time of the DealeyPlaza shooting on 11/22/'63.
He did see him, he was standing right across the landing from him, are you blind?
How could he not see him? Because he must be up on the sixth?
