I had problems with PCC shooters, who were not USPSA shooters, that would 'air gun' while waiting on deck. When I was told after the match, my first question was, "Why were they not DQ'd?" These competitors were not familiar with USPSA rules, but, as match director, there were enough veteran competitors as well as NROI certified people on the squads that I felt it should have been handled at the time of the infraction. I told the entire squad, those that don't know the rules, shame on you, and those that do know and didn't do anything, shame on you. It is a little different than a judgement call on a 180.
