?? I looked at a couple of the examples of scans done on those machines, and I must say I don't 'see' much...certainly nothing that would identify an individual. It is blurry, vague and only barely indicates general body parts/shapes. I cannot comprehend how anyone could work up a 'prurient interest' in blurry gray blobs. I suppose someone wearing 'falsies' might be reluctant to be detected as less well-endowed than they pretend....but sheesh, unless you are famous, who cares?

Now, that opinion has little to do with my take on whether the scans are necessary.
