An officer would have to believe that you had contraband inside of you. If I had contraband inside of me, I would not give you my agreement for an X-ray, and if I had nothing, then I would consent. It does not happen very often. I could provide the committee with statistics, if we compile them. I would have to confirm, but it's not something that's very common.
