I always opt out, so far never asked. Since my ID and boarding pass are packed away, when do they expect me to show my this stuff?? Before the pat down? None of mine require a private screening. I take my molestation in public. Kind of makes sense to log the private screenings. Then you have a record of who was taken to the backroom so they cant claim they were taken. IF it is not in the log, something is really wrong.
