Very few people, comparatively speaking, have had to submit to AIT --- especially at the time this survey was taken.
What was figure quoted by Big Sis: 15 million and counting passengers through the naked scanners since rollout on November 1? Of course, many of those are repeats. However, it strikes me as not a small number. And while I have spoken to some who didn't like the experience and some who have described it as "creepy," I also read comments like "You step in, hold your hands up, wait a few seconds, and then step out. What's the big deal?"
I had hoped and still hope that if the public were to have the opportunity to view some actual leaked images, people might take notice. However, we're four months in now and still nothing has leaked. I am a little surprised by this, but I guess I have to give grudging credit to the TSA and the scanner manufacturers for, so far, keeping a tight lid on this.
