The Christmas Day terror scare has raised new questions about airport security — and information sharing among federal officials. Technology does exist to help spot bomb making materials, called whole body imaging, but the expensive machines are not mandatory because of privacy concerns. But is technology enough? Some say that a form of passenger profiling may be necessary. So tonight, we ask: Should part of enhanced airport security include profiling passengers of certain countries, races and religions? Or does any type of profiling run against our Constitutional beliefs and national ideals? Tell us what you think. You can follow "Nightline" anytime on Twitter: http://twitter.com/Nightline.
