Another problem with this handcuff is that it's too far down on Oswald's hand. It's appears to reach the proximal interphalangeal joint of the index finger. Look where the arrow is pointing.
I know they are called "handcuffs", but they go around the wrist, not the hand. Now, if you think there is a bit of an optical illusion going on there, fine. Maybe. Could be. But, look at your own hand. How far is it from the first interphalangeal joint of your index finger to your wrist? There can't be that much optical illusion.
So, what's the point? The point is that the Jackson photo is an extremely doctored photo. And what they were shooting for was to reassure us that it's no problem that we see no disruption of Oswald's body or his clothing after he was shot for the simple reason that all areas possibly affected happened to get covered up and quite immediately, and according to the Dallas Morning News, in just milliseconds. That's what they said: milliseconds. You realize that a millisecond is 1/1000 of a second. Are you buying that?
