It’s the arrangement of those 3 boxes that had to be completed before the Bronson film starts at 12:25 which is problem. It’s going to be really close if BRW did not leave that window until 12:23 cause the shooter has to wait for BRW to walk abut 160 ft and get on the elevator and operate it before the shooter could be confident BRW was gone from the floor.
The shooter has to walk 100 ft and squeeze thru narrow opening of the box wall and then he has to select which boxes which he wants to use, slide 2 of them in the angle he desired , stack the 3rd box on the window ledge and he has to LOWER the window from its full half open when Rowland saw the black man “hanging out” the window. To the 15.5 in height it was in the Bronson film.
All of this moving of the 3 boxes in place and lowering the window was occurring AFTER Norman was at his 5th floor window from 12:23 till the 12:30 shooting started. Should not Norman heard something?
You make it sound like it was a Herculean task to stack those boxes by the window.
