How can you be so sure? Do you have inside info?
No, I have no inside information. If the schools announce that they were instructed to close by law enforcement, or that they received a threat, then I'd have less problem with the action.
But we haven't heard that, and I don't think we will, since the sniper hasn't been announcing his targets.
He is laughing his butt off over this, I suspect. Gosh, if he shoots someone else tomorrow, maybe the rest of the schools on the east coast will close.
We are feeding his sense of power. We are falling into his trap. We are giving him exactly what he wants.
