Ive calculated that Baker entered the front door of TSBD approx 35 sec post shots
It would have taken only about 5-7 secs more to cross the front foyer heading for the front staircase where Baker draws his gun in preparation to begin ascending a staircase he thought led to the rooftop of TSBD.
So Baker already has gun drawn when he sees Oswald either having opened the storage room door or just having entered.
HEY YOU!! Baker shouts at Oswald, (still wearing his brown shirt.) Do you work here? I need to get to the roof.
Oswald answers: Uh, yea, I work in this building, That staircase doesn’t go to the roof though, only to the 2nd floor.
This bit of conversation takes another
8 secs of time
At this point Truly has entered and sees Baker with gun in hand talking to somebody just out of LOS of Truly
So Truly walks to Baker and then sees Oswald and mistakes Baker thinking Oswald is suspicious because of the gun drawn, and Truly confirms Oswald is an employee.
So this sequence adds the required extra 15 seconds that explain Baker/Truly not opening the “double doors” (as Carolyn Arnold referenced in the Nov 26/63 FBI report) until approx 55 -60sec post shots and after another delay 5-7 seconds as Truly had to unlock the countertop, why Baker/Truly did not start their diagonal trek to rear elevators and staircase until approx 65 sec post shots.
That Is why Baker/Truly did NOT see Adams and Stiles (and vis versa) on rear staircase to 1st floor and A&S exiting the roll up door beside west elevator by 60 sec post shots.
Now the Mrs Reid 2 minute post shots meeting with Oswald in a T-shirt can plausibly be solved
If at 55 to 60 sec post shots, Baker/Truly have left Oswald at the storage room, this gives the following Oswald movement sequence:
1. Returns to storage room to take off his brown shirt = 10 sec
2. Exits storage room in just his T - shirt and walks to passenger elevator= 10 sec
3 Elevator to 2nd floor = 5 sec
4. 50 ft hallway + 30 ft hallway +10ft vestibule at 5ft/sec pace= 90/5= 18
sec
The time of passing in the 2nd floor “vestibule” is therefore at earliest =
43 secs after Baker/Truly leave Oswald at 55 sec post shots, = 98 seconds post shots= TOO late to have a 2nd encounter with Baker at 85 sec post shots on 2nd floor landing.
But it works out perfectly with Mrs Reid meeting because if Oswald enters lunchroom approx 98-100 secs post shots it takes about another 20 secs to walk across floor to Coke machine, buy the coke, walk back across floor, and enter the 2nd floor office rear door at approx 120 sec = 2min post shots
