I think you are 100% wrong. People who assume anything vaguely electronic that they don't understand must be "terrorism" are the problem here, not smart kids building things out of what they have at hand with whatever aesthetic they like. In my opinion, it's the school and the cops who were yelling "fire" in this movie theatre.
And this isn't the first time "the authorities" have go this just as badly wrong: https://en.wikipedia.org/wiki/2007_Boston_bomb_scare https://boingboing.net/2007/09/21/mit-student-arrested.html
