Maybe I’m getting confused in all the finger pointing. I thought HGR said she wasn’t even around when the AD took the gun from the tray. So AB must be used to taking the gun from the AD without witnessing the armourer around the set. That’s a lot of trust, more than I’d have but if that is standard procedure, so be it.
Well, it's not industry wide "standard procedure." It's just this production, out of thousands.
