From the National Review:
It is easy, and in moments of despair such as Friday quite understandable, to scream “more” to gun control, “more” to the morass of airport-style security that is spreading its way across our institutions, “more” to the diagnosis and institutionalization of the mentally ill. But it is much harder to write the laws that would have guaranteed Adam Lanza could never find a gun, or enter a school by force, or go without what diagnosis, treatment, and supervision he might have needed. And hardest of all to write them in such a way that the republic we’d be left with would still look like America in the ways we value most.
This is not so say such laws cannot or should not be written — in the field of mental health, in particular, we think there are commonsense reforms that might make tragedies such as Newtown less likely — but merely to caution humility and care in their crafting.
