Walt. I’m just exhausting all the possibilities of the idea that Oswald looked out ANY window on the 6th floor and saw Jarman and Norman.
I ( and you 2 I think) have already refuted the suggestion by an LN that Oswald looked out the SE corner window and randomly just noticed Norman and Jarman below. It’s a very low probability because Oswald would theoretically have been hiding himself by sitting on that box so his torso is just left of the window (and the pipes)
The only other possibilitiie left was Oswajd at the NE corner of the 6th floor where.he would have had to be hiding waiting for Bonnie Ray Williams to leave the SE window. This about the only way probable that there’s enough time to placed a box on the ledge by 12:25 , just about 1 minute after BRW would have left the window.
In answers to your ? about the score escaoe, imo at the the NE corner window the fire escape is near the ground level so I think there is an LOS that is possible to some persons going around the NE corner of the T:SBD.
However, there are no photos of that NE side of the TSBD building (as far as I know) that show any person at the NE window and No witness statement from any persons from Daltex building seeing anyone in the window either.
It’s of course a moot issue among us CTs as the timeline of 75-90 secs for Oswahd getting to the 2nd floor lunchroom just does not work because of the additional time required for Bob Jackson and Malcolm Couch having to spot the rifle, and then seeing the rifle slowly withdrawn form the window.
And unless there is some evidence found that proves Oswald wore a pair of gloves while firing the MC rifle then that limits the max probable floor crossing speed of Oswald to “double time”” (8ft/sec) to have any reasonable probability he could have wiped wipe off all prints from the rifle while running with the rifle.
