Accomplice, or just an idiot?
The NCO might possibly be Muslim?
My vote, until there is evidence showing otherwise, is ‘idiot’. His thought may have been to prevent the video from going viral and the family members seeing it and/or making the military look bad publicly and/or the muzzies using it as a recruiting tool and bragging/exploitation to advance their filth. I wish he hadn’t ordered the destruction of the videos, but I’m also saying that there are reasonable explanations that would have seemed rational at the time. Time will tell, that is, IF they investigate the non-com who gave the order.
