Such as what? They didn't know about the robbery until shevtold them, they knew nothing about the cheque book incident until she told them. Someone else called the police on her behalf, were the others also coerced? If so, what with?
Such as accessory to murder on the basis JB called JM at circa 3.30 am seeking her opinion as to what action to take based on his claims of a tel call from NB and/or threat of drug related charges.
We don't know who knew what and when and who approached who as there's no reliable evidence eg recorded telephone conversations with a digital time and date stamp. DS Jones claiming LR contacted him is not evidence of anything especially when it can be evidenced he was happy to mislead.
The relatives and James (Jim) Carr claim they suspected JB of OCP burglary pre tragedy. They may well have voiced their opinions to EP who in turn put it to JM. If as I suspect they were able to coerce her into prosecution witness in chief they would tell her in no uncertain terms fess all as the defence will dig deep for dirt to use against you in an attempt to discredit ie what dirt does JB have on you...she may well have fessed up about the cheque book fraud, taking cocaine in a hotel room with 3 others, bringing cannabis into UK from Holland.
Yes possibly all were coerced with the threat of drug related charges: JM, SB, LR, MW, CM, MM, CB and JR.
