Mr O, why are you so damned dishonest.....We both know that the Alyea clip has been posted many times and it shows Lt, Day as he stoops down and grabs the rifle that is LYING ON THE FLOOR with the sling side of the rifle up. (See at 0:44 Of the Alyea clip)
Do you think everybody is so stupid that they can't see that you've posted a copy of Alyea's film that has the frames cropped that show Lt Day stooping down to grab the sling of the rifle.
Thank you for displaying your dishonesty......
I've seen the full film clip. That's why I wrote:
"The film doesn't show the rifle on the floor in-situ,
only after Day has prepared it to be lifted by the strap."
The full film clip begins with Day lifting the rifle from the floor, not with the rifle undisturbed. When the rifle was in-situ, Alyea was filming the Crime Lab photographer. I presume Day would have gently moved apart the boxes supporting the rifle such that the rifle could be lowered on its side and then gently picked up without disturbing prints and so forth. Excellent police work.
