"Three people on the fifth floor heard the three shots and the three pieces of brass hit the floor."
Fair enough, but what about the fellow who was a serviceman on leave and he hit the dirt when he felt a shot ring right past his ear? He was up by the wall over the grassy knoll? They also had another interview with a deaf guy that saw two men up in the parking area directly behind the grassy knoll? One man handed a "railroad worker" a gun, straightened his jacket and walked off into the crowd. The railroad guy broke down the gun and put it in a tool box and he also disappeared into the crowd.
The point is that I wasn't there and you weren't there so we have to rely on second, third and fourth hand accounts. Every year at this time I read reports about the latest or even rehashed "facts" about the assasination and what I find interesting is that every year I hear something that I have never heard before. It's hard to discount any of it because I was not there. But my gut tells me that Lee Harvey didn't have the expertise to pop off three rounds in that time frame with that gun on a moving (away) target. My jury is still out on who else was involved.
