No, you get in an awful lot of trouble if you leak a story , especially involving a crime as serious as this one.
The media will not be allowed to discuss this until it goes to court. No discussions like CNN and Nancy Grace would have at all.
We (the media) are often given stories at 5pm which have a midnight embargo on them. So until midnight you can't do anything or say anything. Papers can do the story (because they won't be out before midnight), radio can have the story in their midnight news bulletin and TV usually has to wait until morning (the 24 hour news stations can run it after midnight)
This is the part that scares me with social media. What happens if WE discuss it here (in America) - if I were in Australia I would get sued but what happens when you are in America? As users of social networks are we supposed to follow the law of Australia from America?
