I'll let the man himself explain.
Charge: Myers misplaces Connally’s jumpseat in order to ensure the alignment of the single bullet theory.
Truth: The location of the jumpseat has no bearing on the alignment of any trajectory plotted in my computer reconstruction. The figures of JFK and JBC were matched to the Zapruder film perspective, not to the location of the jumpseat. Frankly, you could eliminate the entire limousine from the reconstruction and the alignments of JFK and JBC would still be valid since their position in space is based on Zapruder's view of the scene and the relationship of JFK to JBC, and their combined relationship to the TSBD and the surrounding buildings. In short, the position and size of the jumpseat has no bearing on the single bullet theory.

It doesn't matter if you have the correct position of JBC in the car AND if you have an accurate model of the limousine. Myers has neither.
This is Myers' overhead view of his model limousine.:
Jerry Organ's limo model is generally accurate and you can easily see that Myers' limo:
1. has the wrong length to width ratio. It is much too long for the width.
2. This results in him having the side window too far forward. You can see this when you the position of JBC in the two models and see how much farther forward Myers has the side window:
In order to place JBC in the jump seat so that he appears in the same position relative to the side window as seen from Zapruder's position, he has to be moved inboard a significant distance in order for the sightline through the side window to fit what is seen in the zfilm.
Myers' model also does not fit with the positions of the right side window and jump seats as shown in the Hess & Eisenhardt drawing (6 HSCA 50):
And lastly, the paying client by definition must be satisfied, for instance how many defence lawyers have defended an obviously guilty man, the OJ case instantly springs to mind.

A defence lawyer does not give evidence. They are duty bound to defend a client and give the client the benefit of all defences that the evidence and the law permits. They cannot mislead the court and lead evidence that they know to be false. In any event, the purpose of a criminal trial is to determine whether the prosecution has proven its case beyond a reasonable doubt. It is not to determine what likely happened.
