After the Virginia Tech shootings, we heard the usual speeches extolling that such a disaster wouldn't happen again. Well, it has, as have other mass shootings in recent months by people with histories of psychiatric problems. We certainly need a better mental health safety net in this country, but I wonder if all the mental healthcare in the world could prevent such tragedies. A major part of the problem is the widespread availability of weaponry and a culture that celebrates and glorifies violence and bloodshed. Do you think I'm on the right track here?
