When they abduct a helpless victim and torture him and murder him for no reason than to hurt him. If a 6-year-old can do that--he's guilty too. But most 6-year-olds can't. In the case of this boy, there's no evidence he tried to kill anybody. He took a gun to school because this is America where we LOVE guns. It happened again not long ago--a 9-year-old took a gun to school. It fell out of his backpack and discharged wounding another student. If America is willing to tolerate this for the sake of gun rights then fuck em. You get what you pay for.
