He did not identify them. That's not what he was convicted for. He was convicted of publishing snippets of information that would have allowed readers who were aware of other snippets of information to put two and two together and work out who the complainers were.
This is called "jigsaw identification".
Another person was convicted of identifying some of the complainers though. That person tweeted actual names.
Craig Murray was one of about a dozen journalists to have published information which allows jigsaw identification of the complainers, the most prominent of which are BBC and Guardian journalists whose articles and tweets continue to be openly and publicly available.
Please note I am not saying Murray isn't guilty, even though I am aware that there are serious shortcomings in the prosecution case. Having discussed the case with legal professionals, it seems clear to me that the judge quite reasonably found him guilty, even if question marks hang over the prosecution case.
The real problem lies in the fact that the only person prosecuted for jigsaw identification is also the only prominent writer who publicised the defence case brought by Alex Salmond.
The other journalists who published articles that allow even someone completely unfamiliar with the case to identify at least two complainers were all against Salmond.
I am not linking to those articles or naming names, but I will say that Murray's snippets of information were far too obscure for me to identify anyone. He did write a "Yes, Minister" parody after all, which made that even harder. However the BBC and Guardian articles and tweets were far more direct, requiring no mental effort to identify complainers.
The Supreme Court unsurprisingly refused to allow Murray's appeal. If you know anything about the enmity that the UK establishment has expressed towards the former ambassador turned whistleblower about UK collusion with Uzbekistan's torture regime, that was a foregone conclusion.
What concerns me as a freelance journalist is that the judge in this case categorised corporate journalists, like those writing for the BBC and Guardian as legitimate and therefore worthy of special legal protections against a prosecution for jigsaw identification and decreed that independent journalists did not qualify for the same protection. The opportunity this offers to a government seeking to suppress journalism critical of its actions is immense.
