That just illustrates how full of spombleprofglidnoctobuns that you truly are. You could prove that the SBT was impossible if it was in fact impossible. It's a numbers game. Either the numbers work or they don't.
It is a matter of evidence. There is evidence that shows the SBT was impossible. It is just that you don't accept that evidence.
If the witnesses who said that JFK was hit by the first shot (20+) were correct then the second shot SBT is impossible.
If the 40+ witnesses who said that the shot pattern was 1.......2...3 were correct, then the second shot SBT is impossible.
If JBC was sitting in the middle of his seat as he appears to be and if the bullet through JFK did not deflect, then the SBT was impossible at z221-223.
If JFK is already reacting at z223, as the WC concluded and as it appears to many reasonable people, then the SBT at z221-223 is not reasonably possible.
So, on the evidence I accept, the second shot SBT was not reasonably possible. But since you don't accept that evidence for what it says, you disagree.
On the evidence, the SBT did not occur. On the evidence, Oswald fired all three shots and there was no missed shots. One has to discredit the evidence to conclude otherwise.
