Never a JW- I am a white female, who flies to SLC on a regular basis and I have been pulled into the "special room" to be searched and or interrogated three times. I don't think they are profiling me. In fact I travel often and have had that experience in Las Vegas, Baltimore, and Newark in addition to SLC. It's just the luck of the draw sometimes.
As far as the rest of this discussion I agree with Simon this time.
