As above, what would you do if someone set off an explosives detector?
I pat them down, and search their luggage. If I don't find a bomb, I let them go. It should take 3-5 minutes, tops. What I don't do is detain them for hours, grille them over and over again, and deny them food and water during the detainment.
but at the same time they need to be persistent enough to deal with the attempts of guilty parties to conceal the truth.
It doesn't even matter what they say, they either are or aren't carrying a bomb. That can be determined through physical inspection. Persistence doesn't enter into it.
Don't checked luggage go through bomb detection and the like? Actually I'd be inclined to believe they go through even more rigorous checks than people and their carry-on luggage. iirc, they're stored in bomb-resistant containers inside of aircraft, too, ever since a bombing with a bomb in checked luggage some time ago (80's, I think)
