An anonymous reader writes with revelations that the UK government has been pressuring the Guardian over its publication of the Snowden leaks for a while, and that it ultimately ended with GHCQ officials smashing drives of data to pieces. From the article: "The mood toughened just over a month ago, when I received a phone call from the centre of government telling me: 'You've had your fun. Now we want the stuff back.' ... one of the more bizarre moments in the Guardian's long history occurred — with two GCHQ security experts overseeing the destruction of hard drives in the Guardian's basement just to make sure there was nothing in the mangled bits of metal which could possibly be of any interest to passing Chinese agents. 'We can call off the black helicopters,' joked one as we swept up the remains of a MacBook Pro." The paper had repeatedly pointed out how pointless destroying the data was: copies exist, and all reporting on the Snowden leaks is already being edited and published from locations other than the UK.
