John Pistole, TSA Administrator: "On the eve of a major national holiday and less than one year after al Qaida's failed attack last Christmas Day, it is irresponsible for a group to suggest travelers opt out of the very screening that could prevent an attack using non-metallic explosives." http://www.npr.org/blogs/health/2010/11/12/131275949/protest...
That, to me, doesn't jive with their stance that body scanners aren't a big deal because you can opt out. To me, it confirms that opt-out "enhanced pat-downs" were introduced to intimidate people into being scanned.
