Inside a Full-Body-Scanning X-Ray Van

Velcroman1 writes "In August, Slashdotters learned that full-body scanners were roaming the streets in vans: 'The same technology used at airport check points, capable of seeing through clothes and walls, has also been rolling out on US streets where law enforcement agencies have deployed the vans to search for vehicle-based bombs. Fox took a ride in one of the $800,000 vans, videotaping the entire event — and continues the debate about security, privacy, and health risks."

    AS&E says the system is safe for operators and subjects, and that "one scan of the ZBV is equivalent to flying in an airplane at altitude for two minutes."

    and my general understanding is even if you were exposed to a dosage from one of these machines, it would be equivalent to a chest x-ray or less," McCabe told FoxNews.com.

    "Since the police did not have a warrant when they used the device, which was not commonly available to the public, the search was presumptively unreasonable and therefore unconstitutional. The majority opinion argued that a person has an expected privacy in his or her home and therefore, the government cannot conduct unreasonable searches."
