You are absolutedly right, we know what a bomb looks like.
oh wait, not a pair of gym shoes
Unless you think that anything could be a bomb in which case you better stay home.
Well I damn sure know what it takes to make one. After I destroy the first one with a high pressure water jet and find lights, batteries and a light board, but no explosive material, I assure you anyone with any training can - make that - should be able to tell you what this was not. Hours later they are still treating them like bombs. Over reacting, poorly trained, low IQ fools.
