But it's the Z220s double-hit and corresponding simultaneous reactions. Not Z271; that's "Greer shot Kennedy" territory.
Dan and I both agree that JFK was hit in the neck on the first shot. The difference is that Dan is not persuaded that JBC was hit in the back on the second shot. He disagrees with the Connallys' evidence on that point.
No less demanding is the fact that Connally was not hit in the thigh on the first shot. That's how silly your Theory is. Furthermore, 3D analysis shows a bullet transiting Kennedy's neck in the Z190s (your Theory's first shot: Z195) will arrive at a point to the right of Connally's mid-line, not pass by the outside of his left torso (per your failed Theory). That is, if one doesn't use Gumby as a model.
Your disagreement cannot be based on the trajectory. The trajectory is right to left. There is no dispute that JBC's left thigh was in the path of the bullet from JFK's neck.
The dispute is whether his right armpit and wrist was also in that path. But the resolution of that detail flows from the fundamental facts of the case.
A more fundamental issue is whether the bullet through JFK's neck was from the first or second shot. If it was the second, then there must be evidence that the 47+ witnesses who recalled the 1...........2....3 shot pattern evidence and which was mistakenly seared in their memories as the last two shots being closer together, actually heard a 1...2.......3 pattern. Even if you could take every one of those 47+ witnesses and cast doubt on their reliability, you do not end up with evidence of a 1.....2.......3 pattern. You have about 6 witnesses Nellie Connally, Cecil Ault, Gayle Newman, William Newman, Steven Wilson, and Kenneth O’Donnell who thought the pattern was 1....2.......3 and none of them gave a statement to that effect before January 10, 1964 (Ault). Many of the the 1.........2....3 witnesses gave statements immediately after the events with very clear recollections that have lasted to the present time (eg. Robert Jackson).
The three bodies of mutually consistent and independent evidence that:
1. there were three shots.
2. JBC was hit on the second shot and
3. the shot pattern was 1.........2.....3
cannot be reconciled with the second shot SBT. This is why Dan and I eliminate the second shot SBT as a possibility: we agree that the evidence proves 1 and 3. He says it was a first shot SBT. I say there was no SBT - it was 3 shots and 3 hits. Dan's model, the first shot SBT, has better evidentiary support than the second shot SBT because there is less evidence for 2. (JBC hit on shot #2) than there is for 1. (3 shots) and 3. (1........2...3).
A bullet emerging from below the nipple in Z271 travels substantially downward and away from the wrist.
Not unless you think 9 degrees is a substantial downward angle. That is the angle to 12 oclock made by the minute hand at 1.5 minutes after the hour. [At z271 the horizontal angle of a line to the SN relative to the car being arctan(60/275) - 3° = 9°]. The angle through the body is greater than that - roughly the angle of declination of the fifth rib (25°) which is consistent with JBC leaning back about 16 degrees or the angle the minute hand makes at 2.5 minutes after the hour.
Same scenario would work for the wrist injury occurring in the Z220s. The slowed whole bullet would deflect off the wrist and, slowed even more, into the thigh.
Sorry your Theory's first two shots have failed the BS Test. Concede the election.
All I can say is that it is a lot more plausible and a better fit with the wounds and clothing than CE399 doing all that damage, let alone following a bizarre path: passing through the wrist (without making a hole in the shirt cuff) deflecting over to the left side and entering the left thigh in a direction at an oblique angle along the femur, making a nice round hole (as compared to the jagged hole made in the shirt cuff). Tell me how CE399 makes a hole that looks like this in the jacket cuff:
but makes a hole immediately after that looks like this in the back of the shirt cuff.
In fact, if you could get JBC's torso out of the way of the bullet path (by turning his torso to the right - like we see at z195) the bullet exits JFK's neck on a downward right to left path that intersects with the thigh at the correct angle and makes a hole in the trousers and thigh that looks like the butt end of CE399.
It is much easier to see how that could happen than it is to see a bullet from JFK's neck missing his hands in front of his neck passing through JFK's right armpit, exiting the chest pocket and going down to strike his right wrist, deflecting around the radius but still hitting it hard enough to cause a comminuted fracture sending bone shards down into the wrist, passing through the jacket cuff, doubled french cuff (but not exiting through the palm side of the cuff) and moving far enough left to strike the left thigh at an oblique angle that causes it to follow the direction of the femur.
I won't call it a magic bullet because I know you are sensitive about that name. Let's just say that the neck-to-thigh path with CE399 is not any more crazy than the SBT with CE399.
