I wonder how much you read can be believed? Not all troubled kids commit such crimes either; had them as students myself over the years. I’ve had gun vaults all my life, combination in my head. Would have a gun safe prevented this or maybe then he might have just made a pipe bomb or used gasoline. So many questions, no easy answers. Remember, more people are killed by lightning than mass shootings.
You make very valid points.Not all kids (or people,for that matter) commit acts of violence but,all things considered,they might be more prone to such acts than “normal” people.From years of personal experience I can assure you that firearms aren’t the only things that qualify as “deadly weapons”.One vital lesson that must be learned here is the importance of keeping firearms away from certain people,including those with certain psych conditions.
