Yipsy People have been harmed by people discharging firearms, just the way people have been harmed by drunk drivers. That's why it is illegal to discharge a firearm in a freaking neighborhood. So I thank you for agreeing with me.
I don't think we should not punish somebody for drunk driving just because they got lucky and didn't injure someone. In the same way, this guy needs to be punished, because his actions were reckless and negligent.
Should he go to jail? Probably not. But it makes perfect sense to make sure that he and others like him understand that they can't just go shooting at anything that flies near their house. Give him community service at the least. Tell hum if he discharges his firearm unlawfully again, he will lose his right to own a firearm.
