Prior to this tragedy, police may have been able to do more to prevent it. But Georgia's gun laws open the door to these sorts of things happening — and the state's 10th-place ranking for school campus gun violence shows it. It's ridiculous that there's no minimum age requirement for possession of a rifle or shotgun. That allowed the elder Gray to give his son a firearm he never should've been near.
Tragedies like this aren't prevented by violating the Second Amendment rights of law-abiding gun owners. This tragedy tells us more about the level of parenting that's needed in the US — to keep tabs on their children's mental health and make sure they aren't posing a danger to themselves or their community. Holding parents accountable — in this case and others — could reduce the risk of this happening again.
