There is something deeply stupid about assuming that naming your bluetooth device "bomb" is a real threat, let alone that it's going to be a real bomb. Reminds me of all those post Columbine "zero tolerance" policies where kids were punished for marginal doodles of guns. Or the "twitter joke trial". It's as is people are string matching for threat shaped words, not the semantics of a threat.

Mind you, this gets harder when powerful people have got in the habit of making mostly-joking threats on social media themselves.
