Heh, a similar but worse thing happened at the school district I worked in. The principal of a middle school arranged for his friend, a plainclothes officer to barge into a in-session teacher's classroom demanding to know where [student name] is. Can't remember if he had a gun, but I think he did. Class of middle schoolers terrified. The only reason anybody even heard about it is because the teacher, who was not informed beforehand, complained at the district council meeting. Nothing came of it.
