Just stop with this "ZERO reason" (and the "absurd") rhetoric. It's ugly talk, and it's wrongheaded. That the facts of this particular case don't readily indicate mental illness, does not create some bar for the discussion. Where there's extreme violence, I believe there's mental and emotional health issues, whether they are diagnosed or not. Again, the discussion doesn't have to be about banning a schizophrenic from owning a fire arm--the discussion that I want to have is how do we tend to the mental and emotional health needs of our neighbors so they don't get to the point where such violence seems reasonable to them. We need to take a two prong approach 1) stop a person such as this from easily owning a gun 2) stop a person such as this from emotionally getting to the point where such violence is possible. It's the second prong that you're willing to ignore, because you don't want to talk about the first prong. There's probably additional reasons (i.e. more than zero) why it's appropriate to have a mental health discussion when there's mass violence motivated by extreme belief. The need to shut down certain avenues of discussion, well, seems absurd.
