They should have expelled the kid. Imaginary weapons are weapons designed to kill. They have no other purpose than to hurt or maim imaginary creatures (even imaginary people) with as much violence as possible. Does a child really need to have an imaginary grenade? Does he or she need to cause violent imaginary explosives? No. Imaginary weapons not only lead to the pain, suffering, and death of imaginary beings (whose rights are completely ignored by the children), but they desensatize children to violence. Obviously a kid who shoots pretend people with a fake gun is a lot more likely to shoot real people with real guns. All the school did here was potentially prevent a future school shooting by scaring this individual straight. The punishment should be more severe so other children won't begin to copy him though. I hope reason prevails and imaginary weapons are banned from schools nationwide so we can enjoy a peaceful future for kids everywhere.
