OK, I'm not on board with this, and am a bit surprised at the cheerleading for stuff like this. Do you really think the State will use proper discretion for when a parent is culpable in situations like this, or will it inevitably bleed to "every time" punish a parent that gifted someone a firearm?
How many people give their kids a firearm? This is a bad precedent, because it will become the norm, every time..."Oh, you gave your 15 year old a gun, and now at age 25, has committed a crime? Punish the parents!" Remember when civil forfeiture "will only be used against the 'bad guys'?"
