As it is, we have a chain of custody, as established by the testimonies of the principals. McDonald grabbed the gun from Oswald. Carroll took the gun from McDonald's hand. Carroll gave the gun to Hill when they got in the car to take Oswald to the Dallas municipal building.
So far so good.
Not so fast:
Mr. CARROLL. Yes, sir; and then when I got up close enough, I saw a pistol pointing at me so I reached and grabbed the pistol and jerked the pistol away and stuck it In my belt, and then I grabbed Oswald.
Mr. BALL. Who had hold of that pistol at that time?
Mr. CARROLL.
I don't know, sir. I just saw the pistol pointing at me and I grabbed it and jerked it away from whoever had it and that's all, and by that time then the handcuffs were put on Oswald.
