Any author that is going to write a book about the case is going to make Jeremy look more guilty. If the book is going to be anywhere near half decent and accurate.
Even if they also approach the case on the assumption that there was a MOJ. As Harrison did.
There is just so much circumstantial and forensic evidence against Jeremy. As well as the common sense argument that it could not be Sheila. There was also not a MOJ & Jeremy has failed to get off on a technicality.
I don't know what you mean by more guilty.
The fact he was convicted says he is guilty. A good book would lay out the evidence of why he was convicted and his appeals failed. It would thus explain why he was found guilty. That doesn't mae him more guilty it just explains the verdict and establishes why he was found guilty.
A good book would also evaluate the various claims raised by the defense at trial, on appeal and even those not raised on appeal because they were too weak but have been publicly leveled by supporters.
A good book would lay out everything so people unfamilair with the case would be aware of all aspects.
Part of that would entail obtaining information not publicly relesed such as everything to do with the 2009 CCRC submission and rejection so that the arguments made could be spelled out as well as why they were rejected.
That would round out things well.
The person would definitely want to obtain the trial testimony so that it could be accurately quoted from as well- certainly the testimony of the key witnesses. If you are going to write a book you need quotes and references. Otherwise I consider it a wasted effort.
