strake I see why you might post it but it's standard Daily Mail reporting. For those of us (such as yourself) this topic is old, old history. The American military already use this and, I understand, have it set to 'max' and all soft tissue is visible. IIRC (off the top of my head without reading the article) the stated intention for the domestic versions are they are locked to a lower level and the person viewing the image is in a separate location (perhaps 200m away) and notify the local attendants to give a pat down or not. That is, the operator viewing the image, cannot look around the end of the machine and directly see the person they have just scanned. Will images 'leak' out into the web? I'm sure they already have done as these scanners are running elsewhere in the world.
To answer your question: Who gives a monkey's? The operator might think it amusing (or more) for the first half hour but then it will be as boring as the x-ray of bags scanner.
