mikesd81 writes "The Associated Press has an article about Sky Harbor International Airport becoming the country's first to begin testing a controversial new federal screening system that takes X-rays of passenger's bodies in an effort to find concealed explosives and other weapons. From the article: "Critics have said the high-resolution images created by the "backscatter" technology are too invasive. But the Transportation Security Administration adjusted the equipment to make the image look something like a line drawing, while still detecting concealed weapons."
The machines is only supposed to be a backup for when passengers fail a metal detector scan. However, they do get an option of a pat-down or the x-ray machine. Passengers selected for screening by the device are asked to stand in front of the closet-size X-ray unit with the palms of their hands facing out. Then they must turn around for a second screening from behind. The procedure takes about a minute. Critics say the altered image is ineffective and the full image is invasion of privacy."
