I can not even think of standing by and allowing this to happen. Even at the risk or loss of my own life. I am, well, confused. Was there no male presence in this school...none. I would expect for a female teacher to stay with and protect her class. I guess the Marlboro man really is dead.
I would have tried my damnedest to stop him. I'm not talking about a Banzai charge either. It took a little time to do what he did and I'm sure he could have been caught off guard at some point, especially since they have him painted as such a reclusive and timid kid. He certainly looked frail enough that even I could've handled him. We'll never know the truth though so I guess it's all moot.
