This week, as I was in London for the launch of HuffPost UK, Britain's phone hacking scandal mushroomed from journalistic black-eye to a crisis engulfing the UK's most powerful institutions. You know a scandal has reached critical mass when people start asking of those at the top: "What did you know and when did you know it?" So far, Rupert Murdoch is standing by right-hand gal Rebekah Brooks, while David Cameron, who is close to Brooks and had made the now-arrested former News of the World editor Andy Coulson his communications director, felt compelled to toss his chums under the double-decker bus. Big Society, small world. Although filled with journalists behaving badly, it's important to remember that it was journalists, especially the Guardian's Nick Davies and Amelia Hill, who diligently stuck with this story for years and brought it to light -- something the political elite and the paid-off police wouldn't do. Keep checking out HuffPost UK for the latest twists and turns.
