Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

This shows very well the fake forearm that they put in on Leavelle. Look at the ridiculous curve that it takes. The forearm has two long bones, and they are not wet noodles. The elbow is a hinge joint that flexes and extends. You can rotate your hand, but you can't do what he appears to be doing. That is impossible.

What do you think would happen if you tried to duplicate that image? We all know what would happen. It would NEVER look like that. And that's why nobody is going to try. 

They put that in there. Forearms don't look like that, and they don't do that.
