I should think by using the word we, the person who allegedly wrote the letter wanted to give the impression that they are a bigger entity than they are? On the other hand if this is a publicity stunt by PH then it appears to give the impression that it was sent by one of the campaign team? Which I doubt very much? So if a letter was sent it was probably sent by either as scipio suggested a wacko Bamber supporter or a wacko guilter and I know plenty of those. 
But why would the campaign team implicate Jackie and NGB?
This is my take on it Grahame.
1. He disliked what was being said about him on here and the red.
2. Someone had announced he had died (which was not good at all) I can understand his anger at that.
3. Jackie's thread which caused a right ole commotion in which he posted in and appeared rather angry.
4. He then had words with NGB and made threats.
5 He was banned as a consequence of that argument.
6. He was also banned from the red forum
7. He now receives a threat on his life implicating the two people 3 and 4.
8. He discusses the threatening letter with a contact from the police...He does not make a formal complaint.
9. He then gets in touch with the press and hey up!
10. The reporter makes contact with NGB
11. On the Sunday 19th October it is all in Scotland's Sunday Express hitting front page headlines.
12. Its either a publicity campaign to sell his book
13. He does not say the letter is written by a male or female.
14. It is true and it really did occur
15. If its the latter then it is someone who has a deep grudge on NGB and Jackie.
I think its a bag of bol****ks to be honest....
