full body scanners airports Went Unused at Nigeria Airport

The U.S. gave Nigeria four full-body scanners for its international airports in 2008 to detect explosives and drugs, but none were used on the man suspected trying to blow up a Detroit-bound flight, Nigerian officials say.
Since the attempted bombing, the police presence at the Lagos airport has noticeably increased, with officers cradling weathered assault rifles both inside and outside the terminal. Airline officials also are making a point of going through every bag presented to them at check-in.
Full body scanners could soon be looking through passengers’ clothes at almost all U.S. airports. Some are calling it an invasion of privacy, but others say it’s necessary for security.
