Body Scanners

HAMBURG, GERMANY - SEPTEMBER 30: A man demonstrates a check by a full body scanner at Hamburg Airport on September 30, 2010 in Hamburg, Germany. Two scanners are being tested at Hamburg's airport before been installed in other German airports. Full-body scanners are in use to varying degrees in airports across Europe. Following last year's failed Christmas Day bomb attack on a Northwest Airlines plane flying from Amsterdam to Detroit, U.S. Homeland Security officials put pressure on their counterparts around the world to implement security measures like full-body scans. Along with Amsterdam, the machines can be found at airports in cities such as London, Paris and Moscow. (Photo by Joern Pollex/Getty Images)
