I can say that I personally was introduced to fire arms at a the age of 4 or 5 (forgive me for not remembering... it was only 23 to 24 years ago). But that being said, I was shooting a .22 cal single fire rifle and revolver, not a uzi 9mm with full auto! Watching the video shows me 1 thing... the instructor probably was not doing the right thing standing so close to the girl. And 2 if a 9 year old girl was to be shooing a firearm of that sort, I would have been a much more active participant (such as holding the weapon with the child and keeping it on safe until it was time to shoot). Needless to say a 9 year old girl should not have been shooting unassisted or even been aloud to shoot to begin with. That such a caliber weapon on full auto is not easy to control for an adult needless to say a 9 year old girl! Was probably something like whisky throttle when riding a motorcycle. I was never trained on full auto, other than dump 180 rounds and fast as possible down range. But I was 30 in the best shape of my life and able to hump 120 lbs around for weeks at a time in the most difficult terrain you could think of. Not something meant for a 9 year old girl! Stupid policy of the gun range and stupid thinking of the parents. If an grown adult has a hard time handling a single fire weapon what makes you think that a 50 lb child can do the same?
