MTG:
Third, a huge problem with the WC's account is that if Oswald was only one foot past the foyer door when Baker spotted him, as Baker belatedly claimed, then Roy Truly, who was running ahead of Baker, surely would have seen Oswald either coming off the stairs, or walking across the landing toward the door, or opening the door. The Commission itself admitted that Oswald must have gone through the foyer door only "a second or two" before being spotted by Baker:
But the Commission never explained how Oswald could have done this. If Oswald had gone through the foyer door before Truly reached the top of the stairs, he would have been several feet beyond the door by the time Baker reached the landing, and thus would not have been visible to Baker through the window. And, if Oswald had entered the door "only a second or two" before Baker reached the top of the stairwell, then Truly could not have missed seeing him......
Me:
Unless, of course, Oswald lingered inside the foyer-vestibule for a few seconds after entering it and was maybe even peeking back out through the window in the door ("Who's that I hear stomping up the stairs?") enabling Baker to catch a glimpse of him as he quickly turned away and started walking into the lunch room proper (with his bottle-of-Coke prop), especially if Baker swung super-wide in that direction as he turned towards the stairs that led up to the third floor.
Oswald could even have been peeking through the window while Truly was very briefly on the second floor's landing a few seconds earlier.
After all, it was later determined that it would only have taken Oswald about one minute to leave the sniper's nest, stash the carbine, and get to the second-floor lunchroon, arriving there very probably several seconds before Truly emerged from the stairwell onto the second floor's landing.
