This is a lie.
I've always been slightly disgusted by how low you are willing to go.
The last we see of all three agents is z207 and not a single one makes any sign of turning to the right and rear.
You really should be ashamed for peddling this never-ending lie.
You really should try to control your impulsive visceral responses to posts. Lashing out in anger with
ad hominem epithets is not persuasive and universally recognized as poor advocacy. No one is trying to deceive anyone here. As far as Ready beginning his turn to the right, here is Ready from z193-z207. Follow his right hand. it is on the right hand hold in z193. It is down by his right side and his body is turning right by z207:

He is completely turned around to the right rear 2.5 seconds later in Altgens 6. He didn't have time to turn left and then right again between z207 and z255 so I suggest that this is the right turn that he is referring to, which he said he made after the first shot. If you disagree, just explain why.
Another ridiculous lie.
It never ends.
JFK reacts by throwing his hands up towards his throat/chin.
It is not by "moving left".
Are you not ashamed by the endless lies you have to tell?
Do you have no respect for the truth?
Several witnesses directly behind the limo, such as Dave Powers, Ken O'Donnell, Sam Kinney, George Hickey, and Clint Hill, all reported JFK moving to the left and/or slumping to left after the first shot. The fact that you find this so surprising that you suggest it is a lie says more about your lack of knowledge of the evidence than anything else. Again, the
ad hominem approach is the poorest form of debate. You really should try to control that.
