I have been shooting guns with my father and by myself since I was six. He always instilled good safe shooting practices in me and I was well instilled with gun safety by the time I was eleven, and I'm sure if his father was a big hunter he would have taught his child the same (And like I said, judging by the looks of that picture I wouldn't doubt the kid's ability for a second).
ANd remember, we can't let the few kids who DO shoot people with guns spoil it for the millions that do not.
