Of course you dont give an inexperienced shooter a powerful gun. Hes still an idiot. Maybe gun ranges should have an age limit? Or maybe the instructor, who i hope knew something about guns, should have though "oh this is a gun that has a very strong kickback maybe I shouldn't allow the child to use it, considering they are 9 and even if i told them that the gun has kickback their tiny 9 year old muscles could not ever counteract the recoil of an uzi"
A little sense can save lives. And thats why we have laws. Because people lack the sense to do something correctly so it needs be illegal so they dont forget people over
There is something called a Range Officer. The Range Officer's job is to make sure no one is doing anything reckless, dangerous, and harmful the people around them. I'm not sure if they had a range officer or not. If there was one their, he or she was probably too far away to catch what was going on in time.
And yes, many ranges have polices, rules and restrictions. Apparently that particular one did not have such regulations in place. Or they did, but their range officer wasn't in their shooting area to catch it in time and the instructor would be at fault to for letting the girl shoot in the first place.
