And just how, pray tell, does your comment show me up as "wrong?" Did you have something else in mind that you forgot to post? I suggest that it should be policy that teachers be trained and allowed to carry. How does that conflict with your observations? Or is that your all-occasion preface to a reply?
I did not mean my comments to be a personal attack. I was simply trying to point out that no matter how much training a teacher gets, they simply cannot carry. Thus training and licensing doesn't help.
