After reviewing the video I noticed that as the man is walking through the hallway, you can clearly see one of his magazines on the floor before he's even reloaded a single time. He later goes back to retrieve it. It was obviously there before he started. Thoughts?
My guess is that he placed it there shortly before going live in unsuspecting clothing, as part of his elaborate ploy to stir up controversy because he knew it'd spawn conspiracy theories and doubts, furthering the division.
Kind of bad screenshots if you ask me, but you'll know what I mean if you watch it yourself.
