To me, no amount of convenience is worth giving up the privacy that is lost when going through one of those things.

At a minimum, I'm willing to wait in line longer and spend more time at the checkpoint if it means that my privacy isn't invaded. At a maximum, I am prepared for the inconvenience of driving from coast to coast and not flying in commercial aircraft again if these body scanners become mandatory for all passengers.

Perhaps my views are a bit extreme in this instance, but that's simply the way I feel. TSA is an agency that thinks about invasiveness and self-propagation first, with nary a thought toward how their position effectively tramples the Fourth and Fifth Amendments until forced to by the Courts or Congress. So far neither of those institutions have seen fit to rein in TSA in their activities to terrorize the flying public while looking for relatively non-existant and sometimes imaginery threats-- and that's unfortunate.
