Have you never lied.
Or committed a minor, victimless crime when young ? Yes claiming you're cheque book has been stolen is victimless. It was also Susans cheque book, suggesting she was the main force.
You haven't asked if anyone has ever been guilty of cashing in on the death of two six year old boys!
Just to make it clear, I am coming at this from a completely objective point of view. Julie may very well have been telling the truth, but how can you be sure, when her own character is so flawed? It makes her evidence totally unreliable.
Her behaviour, in selling her story would have been disgusting enough, if she'd done it years after the event, but to do it mid enquiry, just weeks after......well, words fail me.
