Btw the killer was seen by several eyewitnesses unloading his gun. The gun that Oswald was arrested with was an exclusive match to the shells found at the scene, which proves beyond all doubt that Oswald's weapon was good enough to produce the matching shells.
“gun that Oswald was arrested with”. LOL
“shells found at the scene”. LOL.
“proves beyond all doubt”. LOL.
“Oswald’s weapon”. LOL.
When the police arrived Ishowed [sic] one of them where I saw this man emptying his gun and we found a shell.

Mr. BALL. Did you see him throw anything away?
Mrs. DAVIS. No.
. . .
Representative FORD. You saw him take the shells out of the gun?
Mrs. DAVIS. No, sir; he was shaking them.
Representative FORD. He was shaking them?
Mrs. DAVIS. He was shaking them. I didn't see him actually use his hand to take them out. I mean he was sort of shaking them out.
Representative FORD. Did you find this one bullet at the point where you saw him shake the gun?
Mrs. DAVIS. No, sir; it was around the side of the house.
I saw the boy cutting across our yard and he was unloading his gun
Mrs. Virginia Davis affidavit 22/11/63
Mr. BELIN. Did you see what he did with the shells when he emptied them into his left hand?
Mrs. DAVIS. After we, well, he was dropping them on the ground because we found two.
Mr. BELIN. You said that you found two? Did you see him drop them on the ground or not?
Mrs. DAVIS. No; we didn't see him.
Mr. BELIN. You just saw him emptying shells in his hand?
Mrs. DAVIS. Yes.
Mr. BELIN. You didn't actually see what he did with them when he got them in his hand, did you?
Mrs. DAVIS. No, sir.
The eyewitnesses saw the Killer manually unload the gun and that's not the way an automatic gun works. And another fact worth noting is that the killer shot Tippit from a close range and the shells were found relatively far away and automatic guns don't send shells that far. Sorry bout that.
And what makes you think the shells in evidence had anything to do with Tippit?
