X-Ray cameras on lampposts .

My first reaction on reading this was surely it is a spoof.Unfortunately not.
According to a memo leaked to The Sun :

X-ray cameras could be installed on lampposts on British streets to spot armed terrorists and other criminals, it has been claimed. According to a leaked memo seen by The Sun, "detection of weapons and explosives will become easier" if the scheme drawn up by Home Office officials is adopted.
However, officials acknowledged it would be highly controversial as the cameras can "see" through clothing.
"The social acceptability of routine intrusive detection measures and the operational
response required in the event of an alarm are likely to be limiting factors," the memo warned.
"Privacy is an issue because the machines see through clothing."

Liberty states that already :

The UK is the world leader in video surveillance. Britain is monitored by 4 million CCTV cameras, making us the most watched nation in the world. There is one CCTV camera for every 14 people in the UK. If you live in London you are likely to be on cameras 300 times a day.

Now with added nakedness.

This latest suggestion for increased surveillance raises further concerns for civil liberties as well as question mark over whether it would make any real impact on the likelihood of an attack and its cost.

Oh and of course the potential for images to end up on You Tube...
