But the retail industry isn't to blame in this case. Parents are. They bought the gun, not the 9 year old kid. They're responsible for the child, and his safety. I think there was a pretty big failure on the part of the parents.
And that, I believe, is the main issue here. Is this not another reason we don't let those under 18 have airsoft guns? Kids are stupid. They don't have the mental capacity to understand what it is they're doing. It's the parents' job to do it for them, not the retailers.
