Could be. I would think it would depend on the situation (as it often does). Given a scenario, such as you described earlier, where police response is measured in hours or days I imagine they may want someone who can respond beyond the classroom.Seems they’d want the room assignment on record so LEO’s know who the good guys with guns are and where they are. Maybe the plan is to get everyone in “safe huddle areas” and guard the entrances rather than sending anyone out to confront the shooter. Maybe that’s practical, maybe it’s not…
