I find the casual assumptions in this thread more than a little disturbing! Starting with the term "lockdown" which quite specifically equates schools with prisons--make what you will of that.

Bomb threats were in vogue a couple of years ago at our local high schools. Here they are always bogus; just stupid copycat stuff. Showed up a bunch of militaristic reactions though.

I guess if you treat people like they're in a dictatorship they will start acting like it.
