> However, this man set off a bomb detector. He set of the machine that detects bombs, repeatedly. After that event, nothing Mr. Mukerjee reported is particularly surprising, and I would expect to have a similar experience if I set off the same detector.
I wouldn't. My bag often sets off the bomb detector repeatedly; when that happens they just search it and send me on my way. It's no big deal. If the bag sets off the bomb detector repeatedly, the most likely reason for it is that the bag was at one point in contact with some chemical that is related to an explosives precursor. And that's OKAY. It's no big deal. You check whether the bag has explosives in it RIGHT NOW, and if it doesn't, you send the guy on his way!
(FWIW, I think I've triggered due to (a) flash paper (a magician's supply), (b) fireworks (of the safe-and-sane variety). In both cases the offending material wasn't actually present, but it had been IN the bag or IN my clothes in the prior week)
