We'd better think about this one. Given that the vast majority of people in the psychobabble / sociologist line of work are flaming, anti-gun liberals, do we really want them to make the determination as to who's entitled to have a gun? I can see this quickly degenerating into a situation where political enemies will be given a mental health assessment detrimental to their ever buying a gun on the legit. market.
Should only citizens have the right to free speech? To remain silent? To be have trials by jury? Etc.
