More in the spirit of daydreaming than anything else, a couple of What Ifs about that prank school shooting:
What if one of the kids had a concealed handgun? One of the teachers pretended to be a gunman trying to get into the building; if an armed kid had seen that mysterious malice thru the window and put a cap in the alleged gunman... wouldn't that have been educational?
And what if some shooter-to-be read about the story and decided the kids had been promised a shooter and been cheated? Then showed up at their school, fully armed, to fulfill that promise? Picture the kids' response to the teachers-who-cried-wolf in that scenario.
"This is not a drill!"
"Heard it, teach."
