He is quite specific that he wants to portray the truth of what happened . So it will be interesting to see if he is portrayed as believing she was capable of the murders. After all it was the family and not him that were arguing with the police about their rushed conclusion. If I was him I would be furious with EP as he could have well not have been convicted. And I still say that today the silencer would not have been admitted as evidence for a start .
i think over time he has been persuaded of jeremys guilt and in the shock had forgotten what he had actually said at the time. shiela certainly had issues that should be taken into consideration and not just dismissed because it suits the guilters argument. the fact is shiela was a poorly young woman, was supposedly odd on the telephone that evening, was vacant etc .
these things have to be take. into consideration as does jbs behaviour
