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.
