yeah, lets blame a kid for breaking a rule we never mentioned. and It's totally okay to overlook the fact that there are people who need medical and psychological treatment, and focus on bullying a little girl in front of them. Such responsible and enlightened behavior.
These "adults" are dumb as hell, even for xenophobes. Do they not care that the other kids are in distress and injured, and will probably view them poorly if they attack her right now? they can justify all they want, but that doesn't work, if the trust is lost.
granted it probably won't matter. the sword is probably cursed, and the kid is probably going to kill everyone but her, anyway.
