As for Texas, this tracks school shootings, not mass shootings. A teacher was shot and injured, students barricaded doors, and it was on a school campus. I think that qualifies—- I would be terrified if that happened to me, wouldn’t you?
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.
Anyway, this is "a shooting at a school" so I think by definition that makes it a school shooting, no?
