Lots of things get lost in translation, blame the media for trying to be the first to press. The part I stated I didn't think he pulled the alarm to draw students into the hallway was just an opinion I drew after reading more about what transpired. It just seemed logical to me that if his intention was to pull the alarm to lure students into the hallway to shoot them he wouldn't have had felt compelled to enter any classrooms, he'd just waited until they started exiting. The fact he got rid of the weapon and blended into the crowd to escape seemed more telling as to why he pulled the alarm.

I looked deeper and did indeed discover that the security drill that morning was a fire drill.

Thanks!
