My work has 'active shooter' training and exercises. It's basically hide and seek. We hide silently, behind closed and hopefully locked, doors, and let the shooter seek others who weren't locked out of the offices (in hallways, restrooms, break areas, etc). Eventually, we'll be 'rescued'. There's no training added for fighting back, protecting one's self, or even for the aftermath. All said...worthless. And worse, it's a place that doesn't allow CCW, nor any knives beyond certain length.
