Privacy activists are up in arms over the use of whole-body imaging at airports.

The systems, which are used in 19 airports by the Transportation Security Administration and give guards a relatively untarnished picture of subjects, were installed after 9/11, but, say foes, they give too much of a view and render people virtually naked. And now they’re calling on the Department of Homeland Security to shut down the devices. Forty-two groups have banded together under the name Privacy Coalition to fulfill their mission.

The TSA, however, defends whole-body imaging, CNN reports: "It is a proven technology, and we are highly confident in its detection abilities."

Though some people suggest head-to-toe pat-downs as an alternative, ACLU lawyer Chris Calabrese disagrees: "A choice between being groped and being stripped, I don’t think we should pretend those are the only choices. People shouldn’t be humiliated by their government in the name of security, nor should they trust that the images will always be kept private."
