But to avoid that we would need a change in culture, and that happens slowly.
Yes, it does. But that’s the real solution.
It’s like getting physically fit; you don’t throw out your television and XBox because you’re fat and sit on your ass instead of going to the gym. You change your habits. The television and XBox are not themselves the problem.
Maybe it’ll lead to just increased incarnation of minorities.
That seems to be the most likely outcome, esp. since prosecutors have fairly broad discretion on charging. I think that making a case for gross negligence would be a different category though, e.g., you knew your child was directly involved in violent criminal behavior and you knowingly left a firearm where you had reason to believe your child could access it easily then you are guilty of being an accessory. But I’d want that bar to be pretty high.
