This wasn’t “negligence” or “accidental”. He was deliberately pointing the gun at the individual. It wasn’t unintentionally pointed at him. It wasn’t accidentally pointed at him. The bullet didn’t unexpectedly ricochet off of something to hit the teen. He deliberately chose to point a gun at another person. That deliberate handling of the gun eliminates the possibility of “negligence”.

I don’t quite know how you didn’t, but you managed to piss off both gun owners and hoplophobes with that comment, and those groups can’t seem to agree on anything else.
