Peter, You can answer the question for yourself....If you've heard Craig describe the action of the police on the sixth floor after the rifle was discovered in the beam of Boone's powerful flashlight.
Craig said that nobody got near the rifle or touched it before Day picked it up.... Well nobody but Day and Fritz got near enough to read any stamping on the rifle AFTER Day picked it up .... There is a film that shows Roger Craig in the background as Day And Fritz are examining the rifle...I'd guess that Craig was at least six feet away at the time and there were boxes of books between him and Fritz....
Walt, Craig did not say anything like "nobody got near it"
Craig said "but we didn't touch it until Capt. Fritz and Lt. Day ...got there"
Walt said, "well nobody but Day and Fritz got near enough to read any stamping on the rifle AFTER Day picked it up"
I have watched the footage and I believe many would agree on what it shows, but it is obvious that it does not show everything.
As a matter of fact, Walt, we see Day and Fritz examining the gun from a few different angles. Sure, I see Craig but it is not clear
because we're watching clips, cuts, close-ups etc and as far as the few moments showing Day and Fritz examining the gun very closely where's the clip.
