I have to disagree. The Guardian has been a bit misleading in that he program has not been banned, it had an injunction against it being shown during the trial of eight men accused of murder during the riots. The BBC can show it any day they want. They just couldn't show it while the court case was running.
This is because the law of contempt is there to ensure that people get a fair trial. Thus a program which could influence the outcome of a trial would find itself "in contempt" if it broke the rules. If you were on trial, you wouldn't want the BBC showing a program which could inflame the jury and maybe result in you being found guilty, not because of the evidence, but because of a fact-fiction film.
That was the problem. It wasn't a "straight" documentary but rather, as the BBC describe it, a "drama-documentary" which mixes fiction with fact.
They are trying to give the impression that the Judge has banned the documentary, which he hasn't. Now that the trial is over, it can be shown any time the BBC wants.
I'm the first to defend press freedom but, more importantly to me, is defending someone's right to a fair trial.
BTW the Judge's name and reasons have to be given in such a case, which it was, it was Mr Justice Faux and his reasons are in the article.
