High-tech airport scans work — too well, say opponents

Some legislators argue that the machines, which cost about $170,000 each and are in use at 19 U.S. airports, could have detected the explosive powder a 23-year-old Nigerian was carrying and should be approved for widespread use. Others, however, call a whole-body scan a "virtual strip search" that should be used only if there's probable cause.
