Well there WAS SOME rifle being stuck out the 6th fioor SE corner window at the very least .
Because Bob Jackson and Malcolm Couch saw SOME rifle (or object resembling a rifle) stuck out the 6th floor SE window and observed it being “”slowly withdrawn”
And there is reason to believe that 3 shots were fired by that rifle per Harold Norman and Amos Euins WC testimony.
Therefore (imo ) the more objective conclusion is that although SOME rifle probably Was from the SE 6th story corner window , it was NOT Likely to be the MC rifle that the Tom Aleya film recorded being lifted by Lt. Day.
Reasons:
1. Harold Norman heard the 3 shots fired in approx 4 sec span per his own video recorded demonstration of the spacing.
2. A 2/3rd majority of ear witness heard the no.2 and no 3 shots too close together to have been plausibly fired by an MC rifle.
3. The absence of any statements made about gunpowder residue found in the barrel or the breech of the MC rifle.
4. No statements regarding gunpowder odor which should have been noticeable.
5. The misaligned scope due to the mount itself requiring shims under the mount = impossible for even a perfectly functional scope to have ever been zeroed using the elevation adjustment nibs.
6. The curiosity of the bolt handle being apparently up and the bolt not locked down.
7. Weitzman seeing a rifle while looking eastward under a flat ie ( thru a pallet) which is not probable if the rifle were between the 2 rows of boxes. If Weitzman is credible , then the rifle must have been moved from its original “well hidden” location to the boxes where it was photographed
Wow!!.... You've really provided a plate full today Zeon .... But #7 is the one that has my attention.....

Weitzman seeing a rifle while looking eastward WEST under a flat ie ( thru a pallet) which is not probable possible if the rifle were between the 2 rows of boxesA) Weitzman was looking toward the WEST.... (see Organ's post Weitzman "E" looking west. )

The camera angle is much steeper than Weitzman's face (which was on the floor) was when he looked beneath the pallet but Weitzman "E" provides a photo of the boxes and pallet where Weitzman saw the rifle LYING ON THE FLOOR.
B)
which is not possible if the rifle were between the 2 rows of boxes The box that is sitting on the floor to the north( right hand side in the photo) of the pallet would have been in Weitzman's line of sight to a rifle that was jammed between boxes of books in the DPD photo .... The official DPD in situ photo shows the carcano standing on it's magazine and sandwiched between cardboard boxes. If the carcano had been there between the boxes it would have been impossible for Weitzman to have seen it when he was down on the floor and shining his flashlight beneath the pallet.
