I have never disputed the fact that a number of witnesses thought the last shot sounded like two.

There were far more who said not however.

As for Kellerman, he heard the two composite sounds of the single head shot sound barrier and muzzle blast and then impact and fragmentation on the windshield area

Clearly all the witnesses you have quoted there were wrong unless there was a missed shot that was never found.

And excuse me, I object to being called a Zealot. I have NO agenda on the assassination. I am and always have been open to a conspiracy. As it stands I think there is virtually nothing to show there was one. And I should know as my opinions on this subject are based partly on extensive academic research and some professional work on the case for highly reputable organisations. And unlike I expect most of you guys here (though I cannot be certain) have met and spoken with many dozens of people who were connected to the case be they witnesses or law enforcement or other.
