When are you people going to stop it with placing Kennedy in a chair, sitting straight up, arms at the side and so forth, to try to make a point? You simply cannot do this. JFK Wasn't seated anywhere near the position of your laser beam figure. JFK's legs were bent, and up against the seat of Connally. His right arm is resting on the side rail of the car, which has to be taken into consideration. He was not sitting straight up and down like your laser beam figure. Period. And this makes a big difference.
After a while this gets ridiculous. (1) JFK's Jacket was "bunched", (2) JFK's Shirt was "Bunched", and now (3) JFK was "Slouched" over. Remember, we are discussing the POTUS, Not a skid row bum sleeping one off.
Now (3) JFK was "Slouched" over? You really think that's something new?
Why not just stand the guy on his head?
