Respectfully, I disagree with this statement.
Action shooting requires a higher awareness of muzzle and trigger finger discipline. A shooter with a high classification has demonstrated, repeatedly and publically, an ability to rapidly and safely negotiate a variety of field courses. If you have the time to spare, I suggest listening to podcasts of GM-level USPSA shooters where they're discussing safety.
The death that started this is shocking and unfortunate, but I don't see a need for rule changes.
P.S. - I'm a nobody who shoots club matches. Take it for what it is worth.
