It might have helped if some of the multiple concerns which were raised about the recent shooter were followed up. And in general, if people with mental health issues had a decent support network, they would hopefully be less likely to fall so low.

Encouraging fathers to remain present in their kids' lives even if the relationship with mother falls apart would help too. Kids having two parents is one of the biggest variables when it comes to success in life, and if I recall correctly, out of the past large scale shooters in the past decade, only one had his dad in his life.
