Claiming there were three shots because of the earwitnesses makes you different in what way? Even your premier go to witness JBC stated he only heard two shots.
His recollection of the days events are the product of him watching the Zapruder film in the hospital. So much for his memory and testimony.
I like how you pretend you don't know that there were three spent shells found in the sniper's nest. While not proof positive, it does corroborate the consensus of the witnesses that there were three shots, including the testimony of the three employees who were directly below Oswald. The three spent shells aren't proof positive of three shots, but I find it extremely unlikely that both the consensus is wrong AND Oswald started with an empty shell in the rifle, because that is the only way there could only have been two shots.
BTW, what do you believe caused Tague's injury?
