...It was a metal case with a digital display on the front. Yes, that looks a hell of a lot like a bomb lol.
Everyone's actions here were entirely justified. Like, a terrorism group isn't going to ask "John Smith" to deliver a bomb for them, are they?
I don't think pictures of the clock have come out yet.
Had the police opened the box, they'd be able to see whether there were explosives inside or not. Then again, maybe they didnt open it for fear of any given bomb autodetonating if you try to open it.
That being said, this was handled very poorly. The kid showed it to his engineering teacher, who recognized it was a clock and advised him not to show any other teachers. It beeped during a lesson, and his english teacher confiscated it. LATER IN THE DAY he was interviewed by teachers and police officers and put into juvenile detention.
The school was not evacuated. The bomb was not immediately moved, the police were not immediately called.
That is what makes this sketchy and Enlightened™. If the teacher was actually concerned about a bomb, they would have reacted differently.
