The idea of mental health screenings for gun purchases is one of those ideas that comes and goes out of vogue fairly regularly. Just yesterday, I touched on a suggestion for just that very thing.
On the surface, and to the uninitiated, it sounds like a great idea. After all, what better way can you come up with to keep guns out of the hands of crazy people than to have actual mental health experts evaluate people first. It sounds great to some folks.
The problem, however, is that a lot of mental health professionals are incredibly biased against guns, to the point that people who represent no risk would be denied firearms.
