The prosecution had an 'unnecessary complication' in that the main prosecution witness did not tell anyone about JB's 'revelations' until 27th Aug and the authorities were not involved until 8th Sept.
It seems to me that the prosecution read through JM's WS's in preparation for the forthcoming trial and homed in on the 'unnecessary complication' hence the following WS dated 8th May 1986.

How do you know JB held a grudge against MM for sleeping with Suzette Ford? From CAL Page 67:
"While she and Jeremy were out in the car, Sue confessed to Jeremy that she had spent a night with Matthew McDonald, although they were both so drunk no sex was involved".
How far do you think they went Caro?
Let's go through it:
1) Police didn't go to her and try to get her to say anything but rather she told a friend about Jeremy.
2) This friend told police what Julie said because even though Julie decided to help Jeremy by not telling all she knew the friend felt no such loyalty and was horrified.
3) Police contacted Julie in response to the story she told her friend
4) She said she decided to come clean to police rather than to say she lied to her friend and continue with the charade. If she was still with him intending to get married then him going to jail would screw up her plans and she would still have a reason to try to lie to protect him but since Since she was not with him anymore that motive to protect him no longer existed so she told them what happened.
5) Police were initially skeptical- particularly about the hitman story- but the level of detail she provided as well as her mother backing up some of the things she said about Jeremy having issues with his family convinced them she was telling the truth.
6) Julie admitted to various wrong things she did that she had no need to admit and that police would never have known about without her admission so her claim she was fully coming clean is supported.
There is no way to try suggesting police made up a story and pressured Julie to advance it. The evidence establishes she advanced this account to someone on her own before speaking to police so how could they have been the source? Police didn't even believer her hitman story because it sounded ridiculous to them so the notion they made it up and had her say it is absurd.
Even if she had lied about everything there is nothing to suggest police asked her to make up such lies let alone helped construct what lies she should tell.
But there is no evidence that she did lie. You choose not to believe her mainly because you say Jeremy is innocent and there is no way for him to be innocent unless she lied.
