Yeah, there are no problems today because backscatter machines are TURNED OFF at many airports and they are doing normal security procedures. Interesting that they'd rather risk people's safety than endure a PR disaster. By not giving people the chance to opt-out, they effectively take control of the story.
So, they turned off these machines for political reasons after insisting they were essential for our safety. Which, if you think about it, is a victory for the people.
