I've just been reading this article in the Spectator about Graham Johnson, who is the main investigator and runs the Bylines Investigator website. The article is from 2023, so written at the time of one of Harry's previous cases.
I can't remember where I found it - if it was on the previous thread, apologies for the repetition.
It has some detail about why many of the cases have not been defended (any comments on this from legal people welcome), and also details how GJ has gone about getting evidence. A couple of interesting extracts:
what’s certain is that Graham Johnson’s methods of gathering evidence against the three newspaper groups has been highly questionable. People who are vulnerable and hard-up have been given money, book deals and the promise of fame in exchange for essentially telling him what he wants to hear. Were a tabloid to behave like that today, heads would roll. Even a source associated with Hacked Off acknowledges that ‘Graham has not behaved well’.
In his memoir about the art of selling lies, Johnson writes about the ‘manufacture of consent’ – if you invent a story and the other person wants to believe it, there’s an unspoken deal.
