When this interrogation starts (and you know it will), I figure I will take two different approaches. I will make the assumption that giving lip or getting in the face of a SPOTNik will result in a retaliatory secondary.

At airports without Cancer Machines, I will probably win an Academy Award playing along, since there is no need for a retaliatory secondary at a pretty safe airport. COS comes to mind.

At airports with NoS where I will opt out anyway (and have even more fun with them), I might as well push back against the SPOTNik, since there a better than even chance of being groped during the opt out anyway.

Regardless of the approach anyone takes, the fact that this interrogation will happen away from the checkpoint means that it will be very easy to audio or video record the confrontation, since you will have easy access to a camera, cell phone, or other recording device. If you observe things, it will be pretty easy to tell if interrogations are going on well in advance of your turn.

My hunch is that the SPOTNiks and their fellow screening clerks will be providing lots of YouTube material soon after this starts.
