witnesses-- Students are still living who witnessed the classroom scenes

It's probably important to interview the students separately to gather up what they think they saw. I would say that these students should start a blog like this one. As I tried to imagine the scene in the classroom from what I've read so far -- and have seen -- on various media-- it seems hard to imagine how the student resistance could be so low. Nobody even threw anything at him, like a desk or chair? Or a book as a distraction? Exactly how this went down should be detailed. Vtech has a creative writing class... get busy.
