It is against the rules to not tell an adult if a kid has a weapon. Maybe you wouldn't have written that rule, but the school this parent sent his child to did, and the parent would be wise to not subvert the authority the school has to make and enforce rules.
He did break the rule, the statement isn't false. He didn't want to tell on a friend, no one does. But he learned that hanging out with friends who break the rules will sometimes get him in trouble too and force him into tough choices over right and wrong. Not a bad lesson at nine, next it will be a friend with cigarettes, a joint, some beer.... What do you want to emphasize to your child? That there are rules, or that the rules don't matter if it's a friend, and he's cool?
I'm not sure what the rules are, or if they require my son to do something.
When the three went down there, the one who brought it was sitting there with his head down, menaing two things.
1) Some other child told an adult.
2) They probably got the knife and the kid confessed.
Why subject the other three to this treatment if it was already being addressed?
You need more hair of the dog, hair, your post betrays dangerous facistic tendencies. Rules were made to be broken, especially the bullshit rules of those Commie Facists of the Teachers Unions, one rule to rule us all!
