re: #13 Kragar

He brought the shotgun. He got at least one other hand gun from a guard he shot.

A guard presumably trained for more than 4 hours (as they want teachers and janitors to do) to handle a gun and react to situations like this. So arming the teachers and janitors at schools is pretty much like telling the assassin “Here are a couple more weapons, you’re welcome!”.

EDIT: Fixed wording.
