You have no way of making sure your kids will never be around loaded guns.
I thusly ask again:
How are you not at all at fault because you refused to give your child the knowledge necessary to safe;y handle being around a loaded gun?[
Believe it or not, there are many American households without a gun. The home I grew up in was such a home. If my friends had a gun in any of their homes, it was never discussed even among us kids. The neighborhood is still safe and secure. We, along with many many of our fellow citizens were never and have never felt threatened, intimidated, outraged or superior enough to insist on living in a gun culture beyond that of sport shooting.
Guns nor irresponsible gun ownership was not a problem until the advent of the cheap, concealable hand gun, the notorious Saturday Night Special.
And yet, we grew up just fine.
