There have already been calls for more extensive use of "profiling", an overly broad expansion of the "no-fly" lists and a lowering of the threshold of what constitutes sufficient grounds to be placed on the terrorism "watch list", and more extensive use of more sophisticated scanning equipment that some have complained are highly intrusive, in that they create a virtual "strip search" image of passengers. Some of the proposals are but a worn out rehashing of the kind of alarmist and bigoted ideas that surfaced after 9/11. They were shot down then, and more thoughtful congressional leaders have shot them down again in recent days.
