Relax.You heard this from another teacher who heard it from someone else yet you post it as a statement of fact, that he told the kids he had a gun in his car. Excellent!
If he had a gun in his car we’d know about it by now since there was a police investigation. If he didn’t have a gun in his car why would he open up a nasty can of worms for himself by lying about it? What could he have possibly gained by making up a story about having a gun in his car? If he is that stupid then he shouldn’t be teaching kids. You must think it inconceivable that someone embellished or that the story morphed as it passed from person to person as they often do. Nope, you with your “inside” information state that he told the kids he had a gun in his car.
He didn’t say the teacher said that as a part of this incident. I read it as something he’d told some other teacher some other time, as if Pofs’ source was talking about him after this incident, and dropped it in as something he’d heard previously in an unrelated way.
You don’t know. So until you do, relax.
