Were there 2 gumans during JFK ination?

I'm not going to say that. What I am going to say is that it isn't very likely even an expert rifleman could make the shot sequence as claimed with that rifle. The primary reason being that the rifle has to be taken down or the shooters head has to move between shots and the target would have to be reacquired for each shot because the bolt would hit the shooter in the forehead during ing. I believe it was reported that a bullet was found on the stretcher. I don't believe any bullet making those hits would survive with only rifling marks as was claimed.
