I've been following today's coverage of the shootings at Virginia Tech. I have colleagues there, which just brings it closer to home how terrible the events were.
Violence like this can happen on any college campus. Let us all be vigilant to watch for those who show signs of stress and emotional trouble, especially in these final weeks of the semester. And not just those who might hurt others, but those who might hurt themselves. Suicide is still the most common type of on-campus death.
