Bravo! Thank you, Katie, for pointing to relevant facts and issues. I would like to see much more and rational discussion of the mental health angle. It will take some of our best minds to craft a decent policy that can/would be enforced. We can start with facts such as you assembled. With extreme vigilance we might be able to avoid liberal ideas such as "NRA members are mentally ill" an idea that is embraced by way too many leftists.
Disclosure: I am a Life Member of the NRA and, before retiring, was licensed to practice clinical psychology.
