The window is not the window at the SE corner of the sixth floor.... That SE corner window was blocked by boxes of books....That's why Sergeant Hill is seen at a different window..... The point remains....Only giraffe man could have stuck his head out of that SE corner window.
I know that's not the SE window
BUT you won't get any honest person saying the SE window was exactly
blocked by boxes.
And didn't Euins say it looked like Oswald was trying to stick his head out the window at some point?
