Before Glenn Greenwald appeared on Newsnight last October to argue the case for the Snowden revelations on a link from Brazil, the presenter that evening, Kirsty Wark, popped into the green room to have a word with the other guests on the show, one of whom was Pauline Neville-Jones, formerly chair of the Joint Intelligence Committee. The interview, she apparently told them, would show that Greenwald was just "a campaigner and an activist", a phrase she later used disparagingly on air.
And so the BBC went after the man, not the story. However, on this occasion, the man held his own rather well, roasting Wark and Neville-Jones with remorseless trial lawyer logic, making them look ill-prepared and silly in the process. At the time, I remember thinking that Edward Snowden had chosen exactly the right person for the job of chief advocate – a smart, unyielding, fundamentalist liberal outsider.
