Seeing as how I just gave you two answers, it's hard for you to claim that your question has never been answered.No jthomas - has never been answered.
So your answer is not owning a firearm yourself......or ever allowing your children to own a firearm?
Even if this is your choice.......how in the world do you keep guns away from your children once they leave home?
My second answer is closer to reality. If you have firearms, you have a responsibility to keep them safely secured. I'd even go so far as to say it should be a legal responsibility. That gets us to "well, what does 'safely secured' even mean?"
On a high shelf in a closet isn't safely secured, IMO, not if you're in a house with kids--they're too damned curious.
