^^^ This (agree with russotto)
Ok, you're 11 years old and your teachers and principal call the local authorities on you because of a project they assigned you to do, but thought the project looked like a suspicious "device"? Can you imagine how scary that would be for a kid that old? Yeah I would say he will need counseling, but for what the school principal put him through. If it were me, I would be trying to tell them what my project was over and over. And maybe this kid was doing that too, but of course, no one was listening to an 11 year old kid. Also I remember enough about science projects in school that in most cases all of them had to be approved by the teachers, initially to make sure it fits in with what lessons are being taught. At least I can't see how a teaching system would get away with just assigning students to go and work on projects, but not really making sure the student is on the right track.
This whole event could now make the kid a social pariah, most of us here probably know how cruel some kids that age range can be to others. I'm not a parent but I would almost guess thats something worth taking legal actions against the school.
