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

Gotcha, Lyin' Lyndon. Look at him! He's already crouching. He was a big tall man who towered over his much shorter wife, yet here on Houston Street, as they are about to turn into Dealey Plaza, he is shorter than she is. This is from the Nix film. 

Lady Bird is sitting up straight and tall, but you can see how slumped Johnson is. He is already getting nervous. He knows what's coming. This is a smoking gun if there ever was one. I should think that this should be admissible in court as evidence of his foreknowledge and guilt. Johnson was 6'4". Lady Bird was 5'6". Do the Math. He is crouching. He knows there is going to be a hail of bullets.
