Look at the color of the socks on the Garage Shooter in the Beers photo. They are light.
Now, look at the socks on Jack Ruby. He's in his prisoner garb, but don't tell me they had him change his socks. This was a city jail, not a prison. Oswald didn't even get a shirt, never mind underwear, which is what socks are.
Different socks means different men!
Who is going to fight about it now, huh? Anybody? Anybody?
