Airport Secured?

You know those really annoying people at airport security checks that are taken to one side because they've got a nail file in their hand luggage despite all the warnings that they are forbidden? Yep, that was us at Heathrow this morning. At first I was pleased that the scanner had found our nail scissors in our wash bag, but, as I pointed out to the guard, I could do a lot more damage with the 6" pen knife that wasn't spotted in our camera bag!
