Thats the whole point (Kate) about being concealed <- no one is supposed to know - but tell the parents and I betcha in a week every kid in that school, would know about the new toy in the classroom to play with.

Yes I do agree at some point somewhere at sometime a teacher may aversely screw up and does revel that she/he is wearing a concealed weapon ? ? Bound to happen. Much like a crazy nut job thats bound to murder in a school.
