What were these kids doing alone in a car and not buckled? Granted they weren't moving, but still, they are in a public place, you don't leave your kids alone to "play" in the car, especially if they can't sit still for more than 5 minutes. This is a case of bad parenting. Teach your kids about gun safety, whether you own a gun or not and you can prevent these incidents from happening. (Cue replies from every angry parent and anti-gun liberal).
