Wasn't there a competition shooter a little while back that drew and fired to prevent a carjacking or something and missed with every round? My Google skills are letting me down as I can't find anything about it now.
I am sure it happened more than once.
I worked with a guy in El Paso in the 90's that shot IPSC. He emptied his 45 at the BG from 3 feet hit 1 time.
Just because someone is a "competitive shooter" does not mean they are any good. We are all competitive with each other, just depends on the venue.
