Regardless if the door was completely shut or almost shut, the fact remains that Oswald was already through the doorway and not, as you previously falsely claimed "opening the door". He was in the corridor. One step to the right and Baker would not have seen him at all.
John, please, try to do better next time. This stuff is way too easy to debunk.
Huh? You're not making sense and you haven't debunked anything because you're not following the evidence!
1. Officer Baker says he might of seen the vestibule door close and Truly who was leading doesn't say anything about the door closing, and Baker definitely says he sees Oswald through the vestibule window.
Mr. DULLES - Had he meanwhile gone on through the door ahead of you?
Mr. BAKER - I can't say whether he had gone on through that door or not. All I did was catch a glance at him, and evidently he was--this door might have been, you know, closing and almost shut at that time.2. Truly came up, round the corner, and started up the stairs yet Oswald was suspiciously lingering in the corridor till after Truly enters the stairwell leading up to the 3rd floor? Because if Oswald's true intention was to get a coke, Oswald would have been well away from the vestibule door window and out of Officer Baker's line of sight, before Officer Baker arrived on the 2nd floor.
Mr. BAKER - At the upper portion of this stairway leading to the second floor, I was just stepping out on to the second floor when I caught this glimpse of this man through this doorway.3. During the time Truly travels from the exit of the stairs from the first floor, across to the entrance of the stairs leading up to the third floor and up a few stairs, Officer Baker still sees Oswald through the vestibule window in the corridor.
4. By the time Officer Baker reaches the vestibule door, Oswald has now decided to not "hang around" but Oswald is suspiciously hurrying out of the corridor and is now about 20 feet away from Officer Baker?
Mr. BAKER - Evidently he was hurrying because at this point here, I was running, and I ran on over here to this door.Mr. BELIN - All right. I see a coke machine off on the left. When you saw Oswald after you got to this doorway inside the lunchroom, had he gone as far as the coke machine?
Mr. BAKER - I didn't notice the coke machine or any item in the room there All I was looking at was the man, and he seemed to be approximately 20 feet down there from me.ConclusionOswald would have heard Truly yelling up the stairs, so Oswald ducked into the vestibule corridor and waited for Truly to leave, then as Oswald was opening the door to continue down the stairs, Oswald unexpectedly saw Officer Baker through the Vestibule door window and Oswald in a blind panic hurriedly moved into the explainable neutral Lunchroom.
Every movement and action Oswald did on the 22nd was the product of a Murderer on the run, fleeing the two crime scenes!
