That is a good video. He nails it on several aspects. The one he doesn’t mention is situational awareness failure. Also, member trying to pull weapon is carrying incorrectly (SOB) for that situation AND stands up after shotgun has been pulled out. Fella holding communion tray should have rushed the shooter immediately when shotgun came up. Probably could have kept him from Shooting second shot. Oh well, it’s over.
I thought he covered that at the beginning of the video.
