It's a very good piece and it's worth noting that David Allen Green (who wrote this and blogs about the law as Jack of Kent - he's a practicing solicitor in the UK) is pretty liberal, not just in his writing but also his actions (he was part of the defence team who got the twitter airport bomb hoax defendant cleared, was involved in the Simon Singh chiropractic libel case on Singh's side) and the New Statesman is a left leaning publication which has frequently published articles in support of Assange.
DAG isn't a man you can easily accuse of being the sort who would be rabidly anti-Assange - almost the opposite.
