He said the letter was postmarked in Essex, I didn't see him mention that he had received threats from the establishment or the Police, im confused here 
Also, I don't think NGB doesn't comes across badly in that article. He clearly states that he doesn't agree with the letter being sent. He also said that some people can be quite fanatical regarding Bamber, and to wait until his book comes out, then form an opinion. No, I don't NGB looks bad in that article at all.
Hi Andrea. In his pm to Jackie where he encouraged her to keep up the good work he mentioned that he had everyone, the police and the establishment try and stop his investigation and indeed even the publication of his book.
So here we have other parties who he has mentioned as being against him. (This pm to Jackie was posted on here by ngb) I just wonder as he appears to have other enemies trying to prevent him publishing, that these enemies might be trying to kill two birds with one stone. Him (he said that they have tried to kill him off on the internet) and also to shift the blame of their threat onto both Jackie, ngb and indeed the "devil incarnate" Bamber himself.
What makes me think this? Well, the obvious. That both Jackie and Bamber are being accepted by their opponents on here as the most likely culprits. But I personally see these accusers and both shallow thinkers, naive and crass.
