If the child was in the tower because the appropriate authority had granted permission = Fine. If just 'got in' = Not Fine.
If the child was in with permission but NOT given permission to make tx - however 'supervised' - then the jump will be high.
The reason that us regular folks don't think it's 'nothing' is because - what other regulations are these people going to think don't apply to them? If they want to take their kids to work, then find a Sunday afternoon GA club.
By the way, make sure that no one with a duplicate name of a 'suspect' comes within 100 miles of our borders. Howsoever it came about, this was VERY stupid.
