I agree with you but I’m curious about something. The Carcano rifle has a 6 round magazine capacity. Of course less if converted to 8 mm as many were by the Germans, but this was a 6.5.
How many, if any, cartridges remained in the mag well after he put it down and left the depository? Presumably they looked for ejected brass as well. It is my understanding that he had time to make only three shots, even though he was an experienced shooter.
Again we’re talking about proof and not conjecture.
On one of the history specials last week, they stated that 3 spent cartridges were found on the floor - one left in the rifle ...
Good question. They would be able to compare the unfired cartridge/bullets to those recovered. On that matter, I believe Oswald was the lone assassin. The only thing that puzzles me though, is the behavior of the “kill” shot. The “magic bullet” that was found was FMJ. However, the brain area had bullet fragments, not a solid bullet found. This is very puzzling to me. Unless, Oswald used different kinds of ammo.
