The gunman didn't stand up until after the last shot.
I think the rifle on the box looked more like this. It's well clear of the window sill. If you think it's impossible for someone to shoulder a rifle, rest a hand or part of the rifle on Box "A" and aim it out of the SN window, I can't help you.
IMO, Brennan saw the gunman crouched for the firing and only saw his chest and waist when the gunman stood up after firing.
Brennan didn't see the man's shoulders and head? I thought he did.

Simply count down six bricks from the top of the window ledge and you will know where the floor inside is located..... A 5' 9" man standing behind that window would have 2/3 of his body above the bottom of the half open window.....So your picture is utter BS!.
