'These lockdowns scare the children'

A retired schoolteacher, raised back east but now living in Edmond, magnanimously respects the right of poor benighted souls to possess firearms "for hunting and self-protection." But what's interesting for the purposes of this blog is what she says about lockdown drills: 

I've held too many in my career. I've had SWAT team practices in my schools after hours to prepare local police for a mass shooting. Do you know how difficult it is to explain to students that they need to practice hiding in their classrooms from those who possess weapons whose sole purpose is the mass shooting of the innocent? These lockdowns alone scare the children.
