Craig Murray is basically a decent guy. He fell out with the British government when he was ambassador to Uzbekistam and broke protocol by protesting about the treatement of Uzbeks by their government - being boiled to death etc. He was subsequently bullied, disciplined and dismissed from his post for acting with humanity and integrity. I think he was traumatised and experienced something akin to a psychotic break, after which he saw conspiracies everywhere in officaldom. I used to follow his blog and it was a mixture of reasonable analysis and unsubstantiated consipiracy theories. In this case, he was clearly in the wrong - he is a blogger with a big following, and he posted material in breach of the injunction. This is why the authorities went for him: (1) breaking a court order, and (2) potentially identifying a sexual assault plaintive. In the UK the authorities don't muck around if you behave like that. This is why he is in prison.
