I think a “true positive” is an issue as well if the protocol to manage it isn’t appropriate. If the kid was armed with something other than nacho cheese, the provocative reaction could have easily set off a tragic chain of events.
Reality is there are guns in schools every day. “Solutions” like this aren’t making anyone safer. School shooters don’t fit this profile - they are planners, not impulsive people hanging out at the social event.
More disturbing is the meh attitude of both the company and the school administration. They almost engineered a tragedy through incompetence, and learned nothing.
