Since Carolyn Arnold did not likely see Oswald as early as 12:12,( other women still present in the 2nd floor lunchroom) nor likely see Oswald exactly at 12:15 if he is the shooter being seen by Rowland at the SW window at 12:15, then the time would have to be 12:17 or later to give the time necessary for Oswald to have retreated from 6th floor after leaving the SW window.
But this scenario kind of interferes with the idea that Oswald moved over and around past BRW to the SE window and just waited there on that east aisle for BRW to leave the floor by about 12:24 and then Oswald placed the boxes by 12:25 just in time to be captured by Bronson film.
If Oswald leaves the 6th floor, he’s probably going to hide the rifle in between some boxes on the 6th floor before he starts down the stairs to go to the 2nd floor lunchroom and be there by 12:17.
It’s seems odd though , to go all the way back down that many floors and into a room where he has no way of knowing if BRW will ever leave the 6th floor , nor much chance to know when and where the JFK limo will be.
For the LN Oswald shooter theorist, what is the explanation?
Did Oswald temporarily lose his nerve upon being spooked by BRW to the point that Oswald was going to abandon his mission entirely? So he went back down 4 flights of stairs to “think about it” in the lunchroom?
What prompted Oswald to “give it another try” at about 12:22, which is about the time he would have to leave the 2nd floor lunchroom to make it back to the 6th floor and able to place a box by 12:25 in the SE window.
The only coincidental thing I’m aware of at 12:22 is the radio transmission that Norman and Jarman heard. But Oswald is in the isolated lunchroom far way from that radio. Was there another radio he could have heard in the lunchroom?
There’s that 12:19 approx siren of the ambulance for the epileptic man. Maybe that siren was heard and Oswald mistook it to as a sign the motorcade might be entering Dealey Plaza? So it’s “now or never” he thinks?
Would Oswald even consider “trying again” at this point since he doesn’t have time to get back to the SE window if he thought the siren was heralding arrival of the motorcade.
In either case, Oswald would still be uncertain about BRW ( presuming BRW was the cause of Oswald’s retreat from the SW window at 12:15), while he is in the 2nd floor lunchroom from 12:17 forward.
Maybe being seen by Carolyn “calms” Oswald down? And then he thought: Maybe this sighting was an opportunity for him to use the lunchroom as his escape plan and alibi. So he decides to go back up to 6th floor just after Carolyn left about 12:18?
Problem is , why didn’t Oswald say something to Will Fritz about his 12:17 meeting with Carolyn Arnold if Oswald had conceived of such meeting as a possible alibi?
