Not much change in the hand position, I agree. But I can't say there is none. There does appear to be a movement of the hat as in z272 the brim covers part of the jacket cuff.
No. It just proves that the hand did not move much at z271-272.
The bullet is exiting under the right nipple in a forward direction. The back of the wrist is against the chest so that the exit point in the jacket pocket and the right jacket cuff are together. The bullet makes a hole in the jacket and a similar hole at the end of the jacket cuff but a very jagged and long hole in the french cuff above the wrist going across the wrist. That is consistent with the bullet striking the back of the radius on an oblique angle, which would cause it to deflect up and to the left.
How so? The wind argument? How does the wind blow it forward - and the left more than the right (if the right moves at all)?
You don't seem to want to deal with his observation. You say he couldn't see JFK's hair. Why? He was standing in the follow-up car and able to see JFK's head. What do you think was blocking his view of JFK? Ok. At least you agree that Hickey's evidence indicates a shot before the head shot. You just think he was mistaken about hearing two shots. And, I gather, you think he didn't hear the shot after the headshot at all.
There is no change in hand position in frames z271 and z272:

This is the moment you insist a bullet explodes out of JBC's chest.
The moment you insist the bullet shatters on impact with his wrist bone leaving metallic particles in his wrist.
The moment some of these fragments of bullet are deflected off (at what must be close to 90 degrees) and crack the windscreen and dent the chrome trim...
...yet JBC's hand does not move one inch after such a tremendous impact.
It is not only an insult to my intelligence but the intelligence of everyone who views this thread to have to read such garbage.
At least you have the balls to take this vital issue on.
Establishing exactly how the shots occurred during the assassination is of vital importance.
But the model you are proposing - first shot at z195 second shot at z271, third shot at z313 - is over.
It's a pity you don't have the balls to face up to that.
And now you've descended to flat out lying:
"You say he couldn't see JFK's hair. "This is just a lie. It's not a misunderstanding or misinterpretation. It's just a lie.
Nowhere in my post did I say Hickey couldn't see JFK's hair. He could obviously see the back of JFK's head.
After having to explain to you how relative positions change as perspective changes, after having to explain to you how blurring affects what is observed, I now have to explain the difference between the back and the front of somebody's head? Really?
Hickey couldn't see the front of JFK's head. Do you really not understand that?
"At least you agree that Hickey's evidence indicates a shot before the head shot."This is just a lie.
You read my post.
It was about how unreliable Hickey's observations are.
He stated JFK sat upright after being slumped to the left. This did not happen. Hickey is wrong about this.
He stated JFK fell forward after being hit in the head. This did not happen. Hickey is wrong about this.
He is an unreliable witness because he is reporting crucial things that did not happen.
And he's your star witness.It's not too late to have a rethink, it just takes a bit of courage.
