Proof??..... A very strong indicator that there were only two spent shells and one live round in evidence on the evening of 11/22/63 is the FACT that the FBI took photos of the evidence ....and the photos they took show only TWO spent shells...and one live round.
And what has this got to do with how many shells were discovered in the SN?
The answer to this question is that it has nothing to do with how many shells were originally discovered in the SN.
The initial reports of officers who were on the 6th floor when Mooney discovered the SN and the shells, explicitly state that there were
three shells.
Tom Alyea, who was with Fritz when he arrived at the SN also reported three shells.
Three shells were originally discovered in the SN.
Your assertion that there were originally two shells is wrong - it's another Walt "fact".
Although none of this is anything to do with when the first shot was fired [the topic of this thread], it is part of the assumption I have based this thread on - that three, clearly audible shots were fired from the SN.
Three shells were originally discovered in the SN. Hank Norman, directly beneath the SN heard three shots being taken directly above him and shells hittiing the floor.
Witnesses saw a man in the SN window pointing a rifle towards the Presidential limo at the same time Norman reports hears the shots being fired from above him [that is to say, he hears shots being fired from the same position the eye-witnesses see the man with the rifle].
Three shots - three shells.
The assumption I'm making is a sound one.
In this thread I have collected an overwhelming amount of evidence demonstrating the first shot occurred at z222/z223. It was the "throat shot" that caused JFK's hands to fly up towards his throat.
Knowing when the first shot happened doesn't throw any light on who took the shots and why, but I've always felt that such a fundamental piece of information relating to the assassination should be
known, and not the subject of multiple, dubious theories.
