I haven't seen any answers to those questions that you say were answered again and again...
And I was noticing in one of the videos where the 2nd guy in white picks up the 2nd object; a cloth gun case according to you...He picks it up with one hand and switches it to the other side of his body while holding it in the center with one hand and supporting the butt of the thing with the other hand...I have never needed two hands to reposition a cloth gun case, of any kind...
You may be looking at the wrong guy. There is one guy that looks like he might be holding some kind of video camera.
The guy I was talking about is at the top of the screen.
