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

The thumb of the Shooter's left hand in the Jackson photo isn't real. It's too long, and it's going the wrong direction. No one could do that; at least, no human. The metacarpal bone for the thumb is much shorter than that of the four fingers, and it goes at at different angle to make the thumb "opposable" to the other fingers. And the thumb only has two phalanges instead of three like the others. So, that thumb is some art that they added. They probably did it to make the hand look bigger because Bookhout had small hands, and Ruby's were much larger. You should realize that the JFK assassination is the most photographically altered event of all time.
