According to your statistics most cops can't either. (70-80% misses.) I am not LE but I have watched them qualify at the local gun club. It is amusing. I don't think those guys that carry huge race guns firing practical pistol matches have any relation to a civilian using a pistol for home defense. Whoever fires the first accurate shot wins. I have never heard of a self defense shooting involving 70 rounds. My strategy would be to answer with a 12 gauge not a pistol. (Reluctantly) Judges are really touchy in Minnesota.
Your reference to "huge race guns" takes the cake for campfire ignorance, and that says a lot.
