You're not ale to grasp it but I'll try one more time and see if it sinks in ........ she had ro tell them about the bank fraud, she had to tell them because Jeremy knew about it and it would have been used to discredit her testimony. She would have been asked if there was ANYTHING in her past that the defence could use against her. So she was left with little choice but to come clean. It was NOTHING to do with guilt or the need to do the right thing - she had NO CHOICE.
The police were then left with a bit of a problem, keep quiet and it would be used to discredit their prize witness. Better to try and plaster over the cracks by 'pretending' (in a moment of guilty clarity) that she and SB went cap in hand to appeal to the bank manager for mercy. While what really happened was tht the police called the head office and smoothed over the issue and it was a formality that JM and SB went to the bank with a police officer - simply to show willing so that if questions were asked there would be at least some evidence to back up the 'story' from JM and SB's statements.
I will say this again so it sinks in.
Julie went to the police via Liz Rimington.
She told them what Jeremy had said & about the caravan break in.
Julie's 1984 cheque book fraud was not in the equation.
Julie had no reason to lie. The police had nothing to blackmail her with.
