Tragedy at VT

I feel for all of the families effected by this tragedy. I also worry for the characterization of people who may be classified as loners or as "mentally ill". Finding a way to defeat these tragedies seems almost insurmountable but I hope that we can learn to better prepare for emergencies and have better "preventative care" for people like Cho, so that fewer of them slip through the cracks. Maybe this incident couldn't have been prevented, I hope in the future some are.
