One of the many things I can't get my head around is how the LN's are constantly saying how Oswald was an idiot, a loaner, couldn't hold down a job etc etc, but at the same time are happy to assert that he was an excellent marksman, fast on his feet, had ninja like abilities and was a one man army. The limit of his abilities are only ever dictated by the point the LN's are trying to make or get out of.
How on earth was he supposed to get from the 'snipers nest', hide his gun between/under boxes, silently traverse across the 6th floor, through a heavy door and down to the 4th floor before two women on that floor leave their position? They probably left by the time he'd pulled his rifle in from the window! Despite all this Dorothy Garner see's nothing.
There's a point where knowledge of the subject doesn't matter because such suggestions are nothing short of laughable. I'm sure by 2025 we'll find out he could teleport!
