the body scans because they don t want the u.s. government to take a nature picture of them they have every right to do that. you say it s necessary but what about the argument it doesn t work? first i think john is encouraging people to opt out of the body scanner and take the pat down. the pat down is designed to find explosives hidden in peoples underwear so it s going to be intrusive. it s not going to be any fun. it s designed to be safe, the images, and designed that your picture can t be preserved or passed on or seen anybody that is looking at you. there is privacy protections build into the whole body imager and to encourage people to take a much more intrusive pat down is the wrong answer. tsa has disputed the argument
