There is no statement as far (as I’m aware) in the JFK witness page from DPD officer Barnett about stopping an Oswald who was then “let go” because Truly vouched for him.
The time would have been between 2 min 30 sec post shots ( earliest) and 3 min sec ps ( latest) by Barnett’s own estimate, of himself locking the TSBD front door.
Pierce Allman met the man he thinks was Oswald , just inside the front door, the door being partly open. ( his video statement)
But if this is Just literally after Baker/Truly entered, and Oswald is there in the doorway, apparently Allman was also oblivious to seeing Baker in the lobby or thru the clear glass doors (2nd set) when Allman does to the phones available in this 1st floor lobby area.
The timing for Allman to reasonably NOT have seen Baker in lobby or with Truly trying to open the counter top desk (thru the 2nd set of glass doors) would have to be approx 65-70 secs post shots when B/T are past this desk office area and traversing towards the rear elevators and stairwell. ( B/T just missed seeing Adams and Styles having exited a side door by the west elevator).
So my estimate for Pierce Allman of approx 60 sec post shots reaching the TSBD front door if the interview with Newmans is 30 sec or less, and distance is approx 250 ft or less is possibly verifiable via an 2013 or later interview with Allman.
Now why Mr Williams on one side and Pauline Sanders on the other side do not see Oswald or Truly is still a mystery
