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

Addendum: When I said you couldn't move them, what I really meant was that you can't move them more than they could conceivably move in .6 second. Now, if you want to mess around with that, I suppose you can. But, we're basically talking about half a second. So, how much can a person move? As soon as you started to budge, you'd be done. 

 I don't think you can even account for the difference we see in Jim Leavelle in .6 second, never mind in Blackie Harrison. 

But, what the hay: if you want to mess with the .6 second, knock yourself out. But, I'll be there yelling, "Go! Stop!"
