You need proof nevill never called bamber. You can't. You can make assumptions
There
is proof that Nevill
didn't call Bamber. At least it reaches the 'beyond reasonable doubt' test.
As long as it's proven scientifically that Sheila was murdered, then Bambers claim that Nevill called him
must be false.
You can't get around that. Legally you can't get around that. It's fixed until somebody can disprove paragraph 518.
None of Bamber's lawyers have ever been able to disprove that evidence. The Judges at the 2002 CoA actually state that Jeremy Bamber's Defence team must have also found the evidence
so compelling that they made no effort to disprove it.
And Jeremy Bamber's defence counsel in the 2002 CoA was Michael Turner QC, a superstar barrister, famous for representing murderers and other criminals. He even freely admits to getting murderers set free, who then go on to murder again.
If paragraph 518 was somehow disproved because of an incorrect interpretation of the evidence, then it still stands that Sheila was murdered, because collectively all the circumstantial evidence makes it so unlikely that she committed the crime. You end up quite quickly reaching a conclusion of Sheila was murdered
'beyond reasonable doubt'.
We also have 37 years of Bamber telling lies, manipulating the evidence, creating fiction. All of it very easy to disprove. An innocent person wouldn't behave like that.
All the smaller pieces of evidence that swirl around and tell a story all
supports Sheila
not killing her family. Nothing supports a Sheila suicide. Nothing. Not even her illness.
The nearest you get in evidential terms to Sheila committing suicide is the gun on the body, and the ballistics expert and pathologist both agree that the gun positioned on the body is 100 percent inconclusive.
the gun on the body could be suicide or it could be murder, therefore it's 50/50 either way, therefore its 100 percent inconclusive.
So, there you have it. Nevill didn't call Bamber.
