WC theory is Oswald was the gunman on the 6th floor at the SW window and then “escaped” from 6th floor , using the staircase, to be seen IN the 2nd floor lunchroom not later than 90 secs post shots.
That insistence that 90 secs is a fixed time that cannot be exceeded causes a problem due to the witnesses like Garner, Adams, Jackson and Couch.
Adams/Stiles (A/S)left the open window on the 4th floor office not later than 15 sec post shots and more likely 5 secs post shots, such that she and reached the ground floor by 60 secs post shots.
The Dillard photo taken of the TBDS approx 10 sec post shots shows an open window at 4th floor office and there is no one in the window. This is a possible confirmation that A/S did in fact leave the office window by 10 sec post shots.
Dorothy Garner, is a problem, because , she stated she followed A/S “almost immediately” and was “right behind them”
She originally had stated that she “saw” the girls going down, but in an interview with Barry Ernest, she amended that to “heard them” on the stairs.
Never the less, “hearing them” still means that Garner must have exited the 4th floor office door by approx not later than 40 sec post shots to have had a reasonable probability of hearing A/S voices/heels on the staircase , since it would be take about 10 sec more for Garner to walk about another 60 ft to be standing near the the stairs at a west window.
Beyond 50 secs post shots, it’s improbable that Garner would have heard any voices/heels or any other noise on the staircase because of 2 floors of separation and the nature of the dogleg type stair that is NOT a continuous “well” type volume as in a parallel staircase.
Also, there is no way that Garner could have seen Baker/Truly (B/T)ascending up to the 4th floor via the staircase after having just seen A/S leave the office and Garner hearing them going down the stairs when she was standing by the west window near the stairs.
The 60 sec time that Adams estimated of reaching the ground floor therefore is probably correct because that’s the only way that A/S and B/T miss seeing each other and also went down before Garner saw B/T ascending up using the stair.
Bob Jackson and Malcolm Couch are tge other 2 witness who mess up the WC not later than 90 sec absolute time stamp.
Jackson’s WC testimony is that it took approx 3 secs post shots before he saw a rifle sticking out the 6th floor SW window of TSBD.
Jackson then stated he said “I see a gun”, then heard someone (Couch? ) ask “”where” and then Jackson pointed to the SW window and stated “in that window”.
Malcolm Couch was probably the one in the same car with Jackson who had asked “where”
Both Jackson and Couch then saw the rifle slowly withdrawn from the window.(3secs?)
The problem caused here is that this adds an approx extra 15 secs of time required for the 6th floor SW gunman/rifle displayer. to exit out from the barricaded SN. ( via Tom Aleya, the boxes originally barricaded the SN so tightly they had to move the boards to get into the SN).
When added to the time required to double time jog (8ft/sec) across 180 ft distance and while simultaneously wiping prints of the rifle, then hiding the rifle between the rows of boxes, Oswald would likely have started down the stairs until approx 50 secs post shots .
Since it has not been demonstrated that a person could go down the dog leg 18 steps staircase and cross about 20 ft of landing any faster than 10 secs/floor, then Oswald could not have started down the 4th floor staircase any sooner than approx 70 secs post shots.
Therefore Dorothy Garner would have to change her statement about following A/S “ almost immediately “ ( 30 sec or less) to something like “Maybe it was more like about 1 min and 15 secs before I came out of the office.
Even if Garner could change that time, however, Oswald still cannot get to the 2nd floor landing any sooner than approx 85 secs post shots a bit to be IN the 2nd floor lunchroom not later than 90 sec post shots.
Conclusion: To make the WC “escape” via staircase theoretically work , without having to completely ignore or dismiss Garner, Adams , Jackson and Couch, requires 2 changes:
1. Mrs Garners statement of time has to be changed from “almost immediately” or the statement must be interpreted to mean a period of time that was at least 1min 15sec.
2. Baker/Truly have to take slightly longer (about 10 secs more) to reach the 2nd floor lunchroom, so the 90 sec time should be considered only an approximation and not as an absolute maximum as the WC seems to suggest.
