I guess it might be because it's just too obvious, given the stories sit cheek-by-jowl in most newspapers, but there's a striking parallel between the two leading stories of the last week that I haven't seen discussed.
Both the gradual revelation of police brutality at the G20 summit and the sudden explosion of the McBride affair confirm the new answer to one of the oldest questions in politics, Quis custodiet ipsos custodes? (or 'who keeps an eye on our guardians?'). And the answer is: anyone with the wish to do so. If you can operate a camera phone at a demonstration or write a blog you can do the job.
Admittedly, Guido Fawkes got hold of the incriminating emails by some yet-to-be-identified means, which one assumes wouldn't be available to anyone. But then who's to say at this stage?
The fact is that it wasn't the usual channels, whether journalists, pressure groups, politicians, or lawyers who gave these stories legs but people who can claim the status of ordinary citizen. I think this is both exciting and comforting.
