So, you’re managing security at an airport. How do you train your bomb sniffing dogs? Well, you might just set up some dummy luggage at a remote site and let the dogs check them out. Or, you could actually put explosives in people’s bags, just to give the dogs something to find…
Which works nicely, in theory… train like you work is a good idea. But what happens when they don’t find the explosives? Right, they get loaded on aircraft, and present a rather nasty surprise for the unsuspecting airline passenger.
