Permitted speech

More news on the progress of 'the Machine', this time about the British visitors to the United States who were arrested and deported for some previous joking tweets:

"If the story is true (and, given that it comes from the Daily Mail, which never lets the facts get in the way of marshalling popular outrage, that is a considerable 'if'), it implies two things:

a. The US border control agency (not the CIA or NSA or some other super-elite agency that hunts threats through the shadows, but the guys who scan passports) has a feed of intelligence gathered from the public Twitter feeds of anyone seeking to enter the US (and possibly other social media connected to their identities). This has a number of implications: where does the data come from? Is it just what is publicly linked to the poster's profile online, or does it come from clandestine sources (i.e., a list of user-generated content sites posted to from the visitor's home internet connection, as hoovered up by ECHELON)? Is there some NSA supercomputer quietly building up profiles on several billion internet users, with parts of these being sent to border security if some other part of the surveillance apparatus detects a keyphrase (say, the words "destroy America") in a feed linked to a particular individual?
b. Given the nature of the tweet (which any reasonable person, had they overheard it in a pub, would conclude was a joke), it implies that, as far as the US Department of Homeland Security is concerned, the entire internet is an airport security zone, where joking about, say, carrying bombs or even an absurdity such as destroying America (how exactly would one go about accomplishing this?) is a punishable offence. There is a reason why joking about bombs at airport security screening lines is prohibited; namely that constraining the allowed range of behaviours whilst passing through a security checkpoint allows the checkpoint to operate. This rationale doesn't extend to applying the same rules to any idle banter uttered by a traveller within earshot of electronic intelligence gathering apparatus, and immediately punishing wisecracks."

They've developed a cover story to protect 'the Machine', as we're not supposed to know about it until the enslavement is complete.
