Fam, an a fukking high school teacher doesn't know that shyt UNLESS they're a REALLY good Physics teacher. Your average teacher ain't trying to rationalize all that shyt.
Stop the noise.
He deserves an apology. I can't say this enough.. But you know damn well your kids wouldn't be allowed to do that shyt. You'd have warned them about that shyt. Don't package clocks in suitcases to mirror some shyt you liked out of the movies or video games and think that shyt is sweet.
We live in a new reality after Columbine et al, so don't pretend you want safer schools and environments yet act like you're so high and mighty not to freak the fukk out when lil buddy walks in with a prop for a halloween costume.
1) Physics Teacher? What he built was not even that impressive to be honest, a PCB board that was pre-programmed to tell time already, connected to a lcd screen, a transformer to changed the voltage from AC to DC, that's elementary radio shack shyt. If a
middle school science teacher can't tell that shyt, they should be fired. Don't they train police to detect for explosives.
2) I do want my kids to be safe, just evacuate the whole school if you think it's a bomb, but they didn't. Because they knew it wasn't.
