We can't stop him from being a bad guy or having mental health issues, but at the very least we could have prevented him from having direct access to fire arms. Maybe if we had a law about people having firearms in a house with mental health issues, the mother wouldn't have had firearms?

Maybe we don't always need to stop the bad guys from getting the guns, but instead stop the good guys from handing him the guns. If this kid did not have direct access to firearms that morning, he might not have killed anyone.
