I'm shocked! The parents and their attorney [how many parents retain an attorney over the '"minor" behavior of a 7 year old?!] aren't throwing the kid under the bus, or even admitting that he's "all boy" [which is code for 'hell on wheels, if you are supposed to be responsible for him].
I think what they really meant was: the kid's a minor, and he's a problem, but when he's in school he's
their problem - we will fight to the death any attempts to send him home when we're enjoying the peace & quiet."
That's what lawyers are for.
