"Portable scanning device" on the Tube ?
The Times reports that
"A small number of plainclothes anti-terror police will be deployed on the Tube. They may be equipped with a portable scanning device that can detect potential suicide bombers"
Really ? Exactly how is this supposed to work ?
Is this a Passive Millimetre Wave Radar "see under your clothes" Camera ?
Or are is The Times getting confused with reports about radiation and chemical weapons sensors or biowarfare agent sampling kits ?
