"The actual threat to privacy posed by these scanners has been inflated using sensationalistic imagery. In order to illustrate how intrusive this 'strip-search' is, civil liberties advocates often display a rather graphic image obtained from a scanner. Yet they neglect to mention that the image is not of an airline passenger but of a TSA employee who volunteered to test the machine. ... To wit, there is virtually no evidence that body scanners have actually harmed Americans. Indeed, civil liberties advocates generally do a poor job of explaining precisely what kind of harm the scanners are supposed to cause."
