Of course it was up to her but that makes no difference to me I still say her behaviour was very strange. You're quick enough to point out every move JB made but leap to Julie's defence at the slightest sign of perceived criticism. I am not accusing her of anything but still say her behaviour right through to the interview after the trial was difficult to understand, imo.
What is difficult to understand?
She loved Jeremy, wanted to be with him instead of visiting him in jail so she didn't rat him out. Even after they broke up she only ratted him out after someone else got the ball rolling. It might have taken her far longer to do it on her own or she may never have done so.
She ratted him out, did a press story assuming it would result in her being left alone, did another story to correct the nonsense they posted and each time the story was in the press they bothered her again but she refused to comment she wanted to move on and be left alone.
