If word gets out that his letters are being used for entertainment purposes then he is hardly likely to continue that correspondence.
I disagree. Following SH's confession, he redacted it a couple of months later and sent out a handful of letters to people on the outside. I was made aware of one letter as the recipient contacted me.
With hindsight I believe he had hoped these letters would make it onto the WWW, after all what did he have to lose?
However what he failed to tell the recipients of the letters was that he was telling prison staff a different story.
Bamber will write to whoever he wants whenever he wants. Even if his letters are published. He has no shame. People like Bamber rely on the loyalty of others to keep the game playing going. He has no loyalties to anyone, as he has showed. He will throw any one under the bus, no matter who they are.
