How on earth would such a diverse group of people conspire and why?
I believe that they all contributed in the framing of 'Jeremy Bamber' , either, 'directly', or 'indirectly', or perhaps ' passively' or 'unknowingly'. Those who are still alive, need to be 'arrested' and 'interviewed', and 'where appropriate' either 'Charged wth conspuring to pervert the course of justice', and or 'not'. I have many examples in my own battle with the South Yorkshire police, the local CPS, and the judiciary from the bottom to the top, and my fair share of witnesses who for one reason or another, 'talk bullshit' [`inventing deliberate and false lies'] , but they say things because 'it helps the police/prosecutions case, and in many instances, 'themselves', either 'financially', or 'because of favour' [ although responsible for 'being responsible' , or 'deeply involved in the commisioning of this' , or 'that' crime, they would 'not be prosecuted'...
'Unfortunately' , such is the nature of human beings, that (1) - if there is only one persons account in 'any set of circumstances', that is 'accepted' , or 'treated' , as 'the actual truth'. However, 'the more witness accounts', 'the more versions of the truth', 'come into play'...
The 'psychology', and the 'intelectual ability' of 'any witness, account' is 'not the same in every instance' , for example, 'most witnesses' are 'intellectually educated' to 'one level' or 'another'...
