Can somebody please just lay it on the line, that the original sound moderator evidence was fabricated?
These days, the authorities are very reliant upon other legal professionals (and the public) believing that the original sound moderator evidence was both genuine and "compelling".
Somebody needs to bluntly point out, that it's not a kosher exhibit. Otherwise, you're just going to be experiencing knock back after knock back, for the remainder of Jeremy Bamber's life.
People understand things in simple terms. They understand, if something is alleged to be dodgy. Once you have got that message across, so that the seed is planted in people's minds, THEN you start going in to more detail.
Instead of being seen to shore-up a genuine exhibit, the authorities have to be portrayed as shoring up a dodgy exhibit. You have to introduce doubt, in order to have any chance of making them look dishonest. Once they look dishonest (by defending an exhibit with so much doubt attached to it) it starts to get more and more uncomfortable for them to continue to defend it.
