edited by me for focus....
One way to tell if people are locked in for testimony at a trial is, the Women's Weekly does not do a four page spread on them, ' I lived with a killer'....' He was good with the horses'.. this kind of thing.. TV, press, Tabloids, all come under the umbrella of it. Gag orders are normal in AU, for a whole lot of reasons, sometimes called a D notice, for 'DESIST'..
There is no need for updates on his family, they are citizens entitled to their privacy, ditto Mick Murphy and his children, any drops to the press are by choice of Mick, and not 'scoops'.. Ditto, the girlfriend. Anyone extracting an interview with her with the idea of publishing it would be subject to sanctions by the court, and very quickly, too.
The legal basis for this is, VICPOL are in charge of info that is required by the Supreme Court. and crossing that line is subject to rather harsh penalties.. Its all a matter of wbo has the authority ... similar to the situation, should they find Mrs Murphy's remains, the minute they are found , they go out of the authority of VICPOL and then come under the auspices of the State Coroner, not the police, not even Mick, they remain so until the Coroner decides to release them to the family..
