I'll preface this w/ my grumpy (I was grumpy BEFORE I read the it. Now I"m grumpier) thoughts:
-my kid would be having a 'sick day'.
-I've been to 'active shooter drill' at my workplace. I do think there is value in drills...what I don't see value in is pretending that the kids need the 'realism' to make it real (and scary) enough. My child has a much MUCH greater chance of being a victim of sexual violence, of her house burning down, of dying in a car crash on the way to daycare tomorrow, etc. than she has of dealing w/ an armed shooter. I hope to teach her, as best I can, how to deal w/ those things--but the way to teach her that is not to 'pretend' she's in those situations in a way designed to scare her.
