I disagree about banning guns. There are other weapons mass murders could use. Anthrax in the mail and homemade bombs have both been used in US history. We cannot reasonably prohibit access to all dangerous materials. Even a large SUV can be used to kill/injury several people.

I think the biggest gains come from focusing on mental health. I see this is just one symptom of a much larger mental health crisis in the US. Other symptoms include high depression rates, high anxiety rates and high addiction rates.
