Airport security: Body scanners now in use and more coming

The Christmas Day attempted terrorist attack on a Delta jet has quickly propelled to the forefront the issue of greater use of airport security equipment that will scan a passenger's full body for hidden weapons or explosives. Two important news stories were published today on the topic.

President Obama's proposed budget for the Homeland Security Departmenrt includes money for hundreds of additional body scanners and other security initiatives, including hiring more federal air marshals. Here's more on that.

Separately, Britain already has deployed scanners at London Heathrow and Manchester airports, two major international gateways,  despite protest from privacy and civil liberties groups, and says you won't fly from those airports if you don't undergo a full body scan. Detail can be found in a British newspaper report.
