Your version of events relies on a unwary assumption of incorruptibility by the police.
On top of that if Julie is such a reliable witness and the circumstances around her statements are sound, The CPS would not keep several of her police interviews and trial preparation documents under PII, and that they have done to this very day.
Far from assumption I posted what happened in chronological order. Doing so demonstrates that she went to someone else who went to the police and then they went to her. It not only demonstrates that she told her account of what Jeremy told her prior to speaking to police but also that police did not believe the story at first. One has to be extremely dense to believe that police would pressure her to make up a hitman story that they didn't even believe and shortly thereafter proved to be false. It requires a lack of common sense to believe such.
Your comment about not trusting police means you are willing to throw common sense out the window and to simply willing to believe they regularly doctor evidence and get witnesses to lie and must have done so here though there is zero evidence and it makes no sense. This is a perfect example of your bias driving you.
That same bias causes you to believe all the nonsense put out by Mike and the campaign team including the bogus claim that there are hidden interviews with police. All her statements were released. Your claim there are hidden interviews is simply you repeating made up propaganda. You do that with great frequency.
