OK - I was watching the news last night and there are now three women who have come forward. Each one had a medical issue that prevented them from going in the scanner and as such, were subject to further searches. Each one had some sort of device attached to them - one was an ostomy bag, one was an insulin pump and I'm not sure they stated what the third was. In each case, how easy would it be to say it was one of these things when it was in fact a bomb? So each were asked to expose themselves enough to see the device and be sure it was safe and then to make sure there was nothing else that could be hidden.
Bottom line, when I fly, I'm thankful for this sort of "invasion". Interestingly enough, most everyone that they interviewed other than the three women felt the same way!
