codguy writes: Up to now, airline passengers have been able opt out of the TSA's Advanced Imaging Technologies (AIT) whole body scanners, and request a physical pat-down for their security check. But ProPublica journalist Julia Angwin points out that a rule change on December 18, 2015 now allows the TSA to compel some passengers to use these scanners instead of giving them a pat-down. The updated rule says, "While passengers may generally decline AIT screening in favor of physical screening, TSA may direct mandatory AIT screening for some passengers," (PDF source). Of course, the criteria for when this can happen is completely unspecified, and one can easily imagine them abusing this by deciding to compel anyone who requests a pat-down to go through the scanners for some reasonable cause from their perspective. Guilty until proven innocent?
