@Enzo,
Interesting point of view... mine is that the instructor had the authority to say no to the girl, to the parents, and to the range owner, if anyone insisted on him instructing/allowing the girl to shoot the Uzi.
Had the girl shot herself, like in the Ma. case, or shot someone else, where would the legal sistem pin responsibility? I think it would be on the instructor, not the parents. Perhaps our resident lawyer
@abisho1 can chime in his $0.02.
I'm still curious to find out all the facts here... if the instructor briefed the girl on how the gun worked, or if he simply put a machine gun in the girl's hand, tried semi-auto mode one time and then switched to full-auto... also, what's the skill level of the girl, prior to this event, and whether or not the parents were insisting on her shooting this gun or it was just because it was part of the "package."
I'm with
@cpb210 on shooting full-auto... it's not for everybody and you definitively need some instruction (which is what was taken place, but obviously not done right), most people can't handle the muzzle rise, so your shots could easily end up flying over the bern, plus you need a lot of ammo to practice. And with a $200 tax added on top of the price and a six-plus month wait to get all the paperwork done, really not for me. But for those who have the money to get one, and pay for training from a good instructor that will teach them how to handle it safely, hey, more power to them...
