[devil's advocate]
Robbins said his son is a good boy who made a bad mistake.
Mah boy's a good boy, he's bringing his life around, oh Lordy yes!
How do we have 11 posts on this story and no one picks up on this line? Granted, the kid is 7 instead of 15. But I think the explanation is that the little boy is "one of us" rather than "one of them." So we aren't picking on him.
When I was 11 years old, I was watching a friend play golf on a local golf course, riding around the perimeter of the course on my bike. All of a sudden the road sign next to me was ringing and cracks were coming from behind me. Some idiot was shooting at me from across the street. I hid behind a guard rail until he ran out of either BB's or interest, then got on my bike and high-tailed it home and called the police. They went and took care of the matter.
Shooting at someone with anything is a violent act, unless it's something relatively safe and consensual like airsoft, paintball or squirt guns.
Accidentally shooting at someone with anything is a violent act. If someone was doing what this boy did, but with a rimfire or centerfire rifle, it could have killed the driver. Heck, if the BB hit the windshield and spiderwebbed the driver's vision on the road he could have been hurt or killed. And shooting across a road (at least in AZ) is a criminal offense. Any road. Can't shoot across a forest road when hunting, or a desert road when setting up long distance target practice, and so on. It's also illegal in AZ to shoot within a quarter mile of a building (unless the building IS a shooting range). And to discharge a firearm INTO a building. And sorry, but BB guns and air rifles count in this regard.
Charging the boy might be a bit absurd, but leaving a 7 year old to his own devices, when he CLEARLY doesn't know his 4 rules of firearm safety and ended up shooting a car, is negligent. If the DA was going to prosecute anyone, it should be the parents. Certainly not felonious, but something in the misdemeanor level that will levy a fine or something. Maybe charge the PARENTS with discharging a firearm across a street, or something.
