Somebody's face they couldn't show
We'll use the 3 Shots version since Backes likes it better.
We are looking at two men in profile but compare the resolution of each man. OH MY FLIPPIN' GOD! How could Oswald come out so crystal clear while the other guy looks like the blob from THE BLOB? He was somebody whose face they didn't want us to see. I'll say it again: He was somebody whose face they didn't want us to see. James Bookhout was a face they didn't want us to see. How do we know? Because we never see him. Nat Pinkston wasn't a face they didn't want us to see because we do see him: at the Midnight Press Conference.
in the hallway at another time:
and even at the Oswald shooting:
And look how they topped off this guy's hat in order to give him more height. Fedora hats were not that high. And compare his ear to Oswald's.
Why WHY WHY does that qualitative difference exist? It's obvious that the man on the left was deliberately obscured. And, he was deliberately obscured because he was James Bookhout.
