If there are two or more shooters, and only one shooter is exposed and made out to be the bad guy, then there is a conspiracy.
Oswald could not have fired a second accurate shot in 2.3 seconds with a bolt action rifle. Cycling the bolt action to get a new round into the chamber and then reacquiring the target with a scope on a moving target in 2.3 seconds is impossible. This was proven by FBI testing.
He was a marginal shooter scoring only at the marksman level in the corp. The cops could not find any gunshot residue on him. So it’s questionable if Oswald himself actually fired the weapon. He said he was a patsy. If the cleanup man, Jack Ruby, had not have silenced him, there would have been many more leads to investigate leading to the truth.

One thing most don’t consider is Oswald could have shot left handed and used his right hand to work the bolt. It is a fairly common technique for left handed shooters.
Oswald could have cycled the bolt action in that time. They even had a 65 year old weapons expert that was able to do this. That is why he had the sniper’s perch.
And a marginal shooter is called a marksman in the Marines. It was hitting a target at 200 yards over open sights. This was a 68 yard shot.
