I make no comment about fault, but I will provide some context.
The shooter had completely shot the stage, then experienced a brain malfunction at the precise moment he was about to hear "if you are finished, unload and show clear" and decided to do a runner to try to pick up steel back at the beginning of the stage. The person who was nearly muzzled was one of the stage RO's, not a "brass/tape rat". The stage briefing included specific mention that the targets at the beginning of the stage would be scored behind the shooter, which that RO was in the process of doing. The shooter had, until that point, followed the normal stage plan on that stage to a tee, which I am sure had lulled the RO into an unfortunate sense of complacency after watching hundreds of shooters doing exactly the same thing for two full days by that point. I am glad that the shooter maintained awareness and nobody ended up with a gun pointed at them.
