This is... er... awkward for me. I live in Blacksburg. Yay me. So I just gotta say that my heart's with the families.
I don't really think the gunman matters here, though. People like him, sadly, become insignificant in the face of their actions. In the end, he's a sad boy whose last act was horrible, but the beauty of the lives lost will, god willing, spread through those who survive them and live on. That's what matters.
