What the hell is a fake bomb? How does a schoolteacher know what a "bomb" looks like? Are we talking about an IED here? That could be literally any fucking thing. I really doubt that this clock looked even remotely like any of the industrially made ready-to-use explosives. Sometimes I can't help feeling like some people should be forcibly removed from the gene pool.
The ignorant portion of our society thinks bombs have flashing lights and tick thanks to Hollywood. In reality anyone wanting to do harm is not going to make their bomb noticeable. It reminds me of the Aqua Teen bomb scare back in 2007 https://en.wikipedia.org/wiki/2007_Boston_bomb_scare

I'm pretty sure the apology was for a more lenient sentence.
