Not at this school, obviously, but still.
Is america employing proper idiot level thickos to the eductation system or what? I get the impression that teachers are supposed to be rational, educated people. If a kid brought in a clock I'd assume it wouldn't cause a bomb scare. I'd give the kid a pat on the back and an arduino to mess with.
In the UK, we're about to give every 11 year old a 'computer'. Basically it's a bit like an arduino with 25 red LED's on it in a 5x5 matrix. EVERY child in the country will be given one for free. I'm looking forward to what they come up with, but a bomb scare won't be on that list of expectations.
What are teachers on in the US? It boggles the mind.
