I've seen a fellow at some of the area 2A rallies that carries a large semi auto pistol in a retention holster with hello kitty stickers on it. Oddly enough...he is never bullied.... go figure.
Now to the point of this thread - school's are generally ran by some pretty irrational people, who teach our kids all sorts of conflicting ideas. #1 being follow the law....unless you don't like it....then just make up BS policy and enforce it as if it trumps the law you are supposed to follow.
That's a great life lesson for our future leaders... don't like the law...just circumvent it and to hell with what the law says!
