9yo takes gun to school, somehow it goes off (concussion/jostling from backpack being dropped on desk), shoots classmate.
Here's the CBS article, with link to another report.
I think the parents & boy should be required to take at least one firearm safety class, maybe repeating it every 2 or 3 years. And the mother who was negligent in storing her pistol should be charged for that. But I don't think the boy could foresee what might happen, so at the most he would be guilty of negligence?
I don't think the boy should be charged with anything, really.
