What I found interesting was the FBI agent who test fired the rifle stated it was impossable for Oswald to fire 5-7 shots in 5-7 seconds.
What I concluded was there had to be a second gun man.
Sorry, but that is a myth. Several shooters have shown that even with the Mannlicher-Caracano three accurate shots could be made. The fact that two struck JFK out of three is the proof. The first shot hit a traffic signal and working the bolt of this gun is quite smooth.
