Gizmodo published 100 photos from a Florida courthouse using a millimeter-wave scanner, much like what is being used in airports. The images were made available using a Freedom Of Information Act (FOIA) request. Our government, and more specifically the TSA, has said that, not only do they not save these images, but that it is not possible to save images from these machines. I particularly like the following wherein it is stated that the machine was sent back with 35,000 images still saved to the device.

To the point, these sample images were removed from the machine in Orlando by the U.S. Marshals for distribution under the FOIA request before the machine was sent back to its manufacturer—images intact.

So, any citizen can request to have these images if they are saved, and our Government is distributing them willingly. Nice.
