I have gone through the opt-out screening at CPH a bunch. It's a lot less hassle at CPH -- if the screeners understand you want to be screened by means other than the strip search machines -- than it is when flying out of a US airport.

Except for those who aren't able to physically take up the surrender position in the machines, it still seems very few are choosing to avoid the strip search machine scans. Most probably aren't aware that they have a choice, and even then many probably don't care. CPH airport was Smith Detections' biggest single non-governmental buyer of these machines. I'm really curious about the money trail.
