Well the violence did occur in a school, and the rest of the school reacted the way they were trained to when they hear gunshots. However I think that to share the same category as other events where students show up distinctly with the purpose of indiscriminate violence and bloodshed, is a bit of a stretch. We are simply disagreeing over Diction, therefore we are both correct :D

Also yes I would be beyond terrified I believe, however I'm not sure that relates to your assertion.
