Nothing about hearing cartridges hitting the floor in the earliest interview.That's right!.... And I believe that IF ? Mr Norman had actually heard the sound of shells hitting the floor in conjunction with the sounds of a rifle bolt being operated and the boom of the discharge....He wouldn't have been standing there scratching his head and wondering what he'd heard....He would probably said something like "Hey! ...There's someone firing a rifle right above us.... Let's get outta here"....Norman didn't start talking about shells hitting the floor until the FBI questioned the three stooges a couple of days after the coup d e'tat. They "re-enacted" the THEORY about the shooting while Hero Hank was on the fifth floor straining to hear the sounds they were making in "re-enacting the shooting" That's when the sounds were actually introduced into Hank's memory banks.
Conspiracy cannot be eliminated to a 100% certainty yet I?ve seen no hard credible evidence for it in 56 years.
As the old saying goes, "There are none so blind as those who will not see."
Ever been to the Plaza, Robert? Ever lit a firecracker there? It is an echo chamber....... chamber.
Maybe you should open your eyes.......
