The ProVision "image-free" upgrade, for instance, replaces the 3-D black and white silhouette of the passenger with a "generic, computer-generated outline of a person," according to the TSA.
(emphasis mine)
What's the difference between a "silhouette" and an "outline"?
(from merriam-Webster.com)
Silhouette: (2) The outline of a body viewed as circumscribing a mass.
Outline: (1a) A line that marks the outer limits of an object or figure.
So I guess they are replacing one system with another that is indistinguishable from the last one. Now that's neutral, unbiased reporting for you. You'd think we actually had a government controlled press.
