Highest number of deaths? How many were killed in Columbine? Cuz that was considered the worst before, right? 15 or something? *shrugs*
Yeah they said he was walking around specifically looking for teachers.. maybe the students tried to stop him... cuz there was a girl they had on the news that said that like she saw the guy kill one of the teachers, look at her, and just walk off... And another said he saw the guy reloading or something in a hallway and then keep walking around... And yeah since most of the dead were teachers...
But that's what happens when someone gets extremely pissed off, has access to weapons, and the brains (as in screwed up brains) to do it...
