I don't know who rotates their torso other than from their spine.
Everyone rotates their torso around their longitudinal axis.
If the spine rotates around some notional body axis, then the spine would have to physically move laterally every time we turned,
That is correct. Connally's spine moved laterally to the left when he rotated to the right. Not much, but move it did.
which means that the hips would have to move.
Not necessarily. But I'm not arguing that Connally never moved his hips either.
What you need to do is show us a video of someone turning right 30 degrees from forward and show us how their right shoulder moves left 3 inches.
Nope.
I am just saying that:
1. suppose he was closer to 10.2 cm inboard, say 13 cm (5.1 inches). and say
2. the first shot struck JFK in the neck at z195 (which, unlike the phantom missed shot at z155 or so which no one observed and which conflicts with at least 3 large bodies of mutually consistent evidence, fits the evidence) when the angle from the SN to the car direction was about 13 or 14 degrees.
Then the bullet through JFK's neck crossed the plane of JBC's jumpseat an additional 14-15 cm further left. If JBC's spine was 13 cm left of JFK's then the bullet would have passed to the left of JBC's spine by 1-2 cm. But at z195, JBC was turned so the plane of his back was aligned generally in the same direction as the right to left bullet path so the bullet would not necessarily have struck his back. We know it didn't. But that was not the only part of his body that was on the left side of the middle of his jumpseat. And there was a wound on his left side. What is "invalid" about that?
The SBT tries to drive a square peg into a round hole. No one said it had occurred and many said it didn't. There is another explanation that does not conflict with the evidence but is still consistent with the overwhelming evidence that all shots were fired using Oswald's MC.
The SBT does not try to drive a square peg into a round hole, but I know something that does.
