Still waiting for Anyone to reveal Why SA Hickey is seated so Exceptionally High inside the Queen Mary. His head is higher than the front windshield, and Much higher than everyone else inside the vehicle. Extremely peculiar.
SA Hickey appears to be either sitting on a very high booster seat or he is partially standing from at least as early as z138. His head is higher than others who are seated but lower than the agents standing on the running boards. At around z150 he begins to lean over to the left and looks to the left and down. He appears to be trying to look at something or someone through the space between McIntyre and Clint Hill, perhaps the left rear motorcycle outrider. He is not extended outside the car so he can't be looking at tires.
He appears to stop leaning left by z175 but keeps looking left (head turned left) as is seen in Betzner's photo at z186 (which Betzner indicated was before he heard a shot). He then starts to rise after z198 until z207 which is the last zframe in which he is seen. This can be seen as an increase in the amount of his chest/white shirt that is visible above the central roof support bar. It can also be seen in the difference in his height between Betzner (z186) and Willis No. 5 (z202). By z202 (Willis 5) he is looking forward. By z256 (Altgens no. 6) he is looking to the rear. We cannot see him between z207 and z256 or after z256.
According to his evidence Hickey turned around to face forward before the second shot and remained facing forward until after the third shot as he states he was looking at the President on both those shots. He said he thought the second shot did not strike the President because all that he could see was the hair on the right side of his head lift up. He said that he saw the third shot strike him in the head.
