the kid assembled a "suitcase bomb" prop and kept showing it off to his friends during class. His teacher told him to stop, he didn't and kept being disruptive. Obviously calling the cops on his bad behaviour is overkill, but the he is no wunderkind as portrayed by the media (and even the WH).
he literally said something like 'that's nice but it looks like a bomb. don't show anyone else.' -- it doesn't seem to me to be unsupportive, just worried. I don't think a teacher would say something like that in confidence with a student unless that student had a certain rapport with the teacher.
