With the threat of terrorism back in the headlines, so is the question of privacy versus security:

A suspected terrorist’s attempt to blow up a U.S. airliner may override privacy concerns and intensify a push for full-body scanning equipment at airports as the U.S. plans to buy more of the machines.

And to make clear what we're talking about:

A spokesman for a company that makes the machine says that:

... his company has mitigated that [privacy] concern by blurring body images and having technicians viewing the images in a different location from the screening equipment.

... but is it enough?

Where do you stand? An unnecessary invasion of privacy or a necessary trade-off in a dangerous world?
