I found this while looking for some additional information:
From an IPSC forum, the video didn't start at the beginning of the COF...
"the poor patcher has quite severe hearing problems, and before the video started recording (The COF had already started before the video started, as the shooter had his gun out and on the table for a tabletop start.) the RO had loudly asked "Range Clear?" and received no response from the patcher (because he couldn't hear the RO), so the RO believed the range to be clear and started the next shooter."
I'm sure he volunteered and they don't pay him but, it seems to me that a guy with "severe hearing problems" may not be the best candidate to be downrange during a shooting competition.
