I agree with nancyf and gobuckeyes that I won't let TSA prevent me from traveling. I have been pulled out of line for patdown twice, both times before this new procedure. The last time was in Boston in August after I had been through the detector, and I don't know why. The previous time was several years ago at LAX after spending the night at a hotel on the way back from Australia. My friend had already gone through, and she told me that the security people were counting and pulling out about every 20 people.
When my sister and I went to Israel in 1993, it was a very quiet time and our guide took us to places he wouldn't take friends a few months later. We flew SwissAir from Boston through Zurich, and the only thing different was that we were bussed from the terminal in Zurich to our plane way out and had to identify our luggage and any appliances like hair dryers. But we had changed one of our flights within Israel, and that led to a lot of questioning at the airport in Eilat. Questions about why we had visited Israel, what was our relationship to each other, why we had changed the flight. Not unfriendly, but very businesslike.
I am going to San Antonio next month and will opt for the detector rather than the patdown, now that it's so intrusive. If anyone wants to get their jollys looking at x-ray's of a 78 year old woman, that's their problem.
I also agree that profiling would be much more effective.
