This is a tragedy and I feel for the family of the deceased.
It's also a man bites dog story. In that its so rare as to be news worthy. Millions of rounds are fired every year around the world by people running around at full tilt with guns that aren't drop safe. The stars aligned really badly this one time to make this happen. But its in fact only this one time. We don't need to change entire sports because of this. We don't need new rules books and we don't need to change all our guns. More people die playing golf.
Lets all read the cover of the Hitchhikers Guide and DON'T PANIC!
