...and study the link between college shootings and mental illness
What's to study? Does anyone think there's not a causal relationship? There are hidden agendas here. (1) Take away guns. (2) Overprescribe anti-psychotics. Option (3) allow legal carry for everyone else is not even open for discussion.
Sure, there is a hidden agenda here. As a gun-grabber once told me, any one who wants to own a gun should pass a mental health test administered by a pyscologist. And, then he added, and any one who wants to own a gun is, by definition, mentally ill. Therefore, no one would pass the evaluation.
