Why would you do this and take it so school to show off? Fucking why? The kid's either an idiot or the reincarnation of PT Barnum.
or he wanted to show it to his teacher... exactly as he said.
But given all the possible projects he could've worked or possible other clock cases he could've used to "show off" at school, why pick the one that makes it look like a Hollywood prop bomb and even plug it in during the middle of class when he should be paying attention to the lesson?
When I originally heard about the story, I thought he had made a cut out in the case so that the display would pop through it and be seen and the clock could be used when the case was closed and locked. That would actually be kind of cool and artsy, like a case mod. Instead, we have a Hollywood bomb replica that as Trausti's video shows only takes about a minute to make (we'll give him 5 minutes, since he is 14 after all).
Now, I'm not saying there is no legitimate purpose in doing what he did. It can be a good learning experience to explore the components of a clock to learn why it was built that way and whether the construction can be improved upon. However, the choice of case and the way he put it in the case is, at the very least, suspect.
From the schools perspective, they wanted to try to determine if he had any intent to try to alarm people. The police did not find enough convincing evidence of his intent to charge him with anything, but the school still thought it was suspicious enough to warrant suspension. Given zero tolorence attitudes in schools (which are overboard), the suspension can be easily explained by that rather than him being a Muslim.
We have not heard the full story from the police, but putting him in handcuffs, based on everything we know, is overboard. Not allowing him a lawyer or parent present during question doesn't make sense either. However, what happened to him seems quite petty in comparison to other problems out there and other people who really are brutally victimized.
