Well, if I've nicely hidden my expensive digital camera away from prying eyes of some thief, I think I'd be pretty annoyed if "security" is showing pictures to one and all (including said thief), of where to go ferreting around in my bag, while their partner in crime distracts me.
I always thought that the idea of personal baggage security was that you loaded your bag into the x-ray machine, passed yourself through the metal detector and then collected your bag as it emerges from the machine... So at what point does the would be thief get to rifle through your bag? And what are you doing whilst it is being rifled?
Would be thief and partner in crime hanging around the xray machine? I think not, the much hated yellow jackets wont let anyone hang around in this area. Outside of this area the security of your hand baggage is entirely down to you. Don't let it out of your sight, better still don't let it out of your hand lest the same yellow jackets take it away and blow it up!
