Special to CNN
After a failed Christmas Day terrorist plot on a U.S.-bound international flight, the airline passenger screening process has received heavy scrutiny from the government, the media and the public.
Questions abound about how a Nigerian national who was supposedly on the terrorist "watch list" was able to obtain a visa, fly to the United States and transport explosive materials undetected.
The screening process at U.S. airports has received particular scrutiny in this case - and rightfully so. Whole Body Imaging scanners being tested at many airports have the potential to detect explosives. But these invasive machines perform a virtual strip search, producing detailed images of a passenger's body.
Screeners can literally count the change in a passenger's pocket, see the sweat on his back, and view intimate gender-specific details when looking at the image.
We must carefully consider how to balance safety and security with personal privacy concerns. In the wake of an attempted attack, there is always pressure to surrender more of our liberties in the name of security. It should be our goal to employ technologies that are more effective and less invasive.
