North Carolina has a "safe storage" law pertaining to guns--you have to "secure" your firearms where minors can't get to them, or face charges.
I think this law, like most laws regarding firearms, is a Bad Thing. I understand the intent, but if you have guns in the house, you're far better off de-mystifying them to your kids. Teach them the 4 Rules, teach them to respect the destructive power of a firearm and teach them the proper use of a firearm.
Because they may be caught alone at home when some armed nutjob decides to break in. It's a damned shame that a 14 year old had to shoot someone, but it's far better that than what was likely going to happen if he hadn't shot him.
