Not to cause Mr Mytton to post rolling eyes smileys, but it just occurred to me that if Oswald is PM that there might be yet one more speculative reason why Oswald seemed to be anxious to return to his boarding house ASAP.
Because Oswald heard the shots while on the steps and recognized them sounding uncannily similar to how he remembered his own rifle sounded when firing 6.5 mm ammo.
If Oswald had removed his rifle from
Paines garage in Oct 63 and relocated it to keep it at his boarding room , and Oswald was also aware FBI were surveillmg him, then it’s not so implausible that hearing shots similar to his rifle might prompt a paranoid feeling of impending “set up” in progress.
Since Oswald theoretically therefore was seeking to leave TSBD ASAP, then if he met Baker/Truly as early as 35 sec post shots at the TSBD entrance door or just in the 1st floor lobby , then what accounts for Oswald lingering for almost 2 min inside the lobby such that he is able to have meeting with Pierce Allman (reporter) approx 2:15 sec post shots?
Allman was interviewing the Newman’s on the grassy knoll before he traveled To the TSBD so it’s probable he did not enter TSBD any earlier than about 2 min post shots
If Allmans story is true, then the timing of Allmans encounter with Oswald coincides better with a scenario of Oswald having followed AFTER Baker/Truly entered TSBD and Oswald used the passenger elevator to 2nd floor which speeds up his arrival time entering the 2nd floor (from hallway) lunchroom to coincide with Baker/Truly using rear staircase to arrive approx 80-85 sec post shots
Oswald returning to retrieve his jacket from the 2nd floor lunchroom, runs into Baker/Truly 85-90 sec post shots
Oswald leaves 2nd floor lunchroom 15 sec later , ( with jacket on) goes down rear staircase , crosses 1st floor, thru Truly counter top ( left open by Truly) and into the lobby (30 secs travel time)
Total time elapsed: 135 secs post shots = 2 min 15 sec post shots.
