That's not really how things work, though.
I mean, if you take the position that nobody should ever accuse anyone of one thing after themselves being accused of another thing, that's up to you.
But when people make a claim - say, that there was no justification for handcuffing Lucy Letby; or there was important information missing from the Countess of Chester report to the pathologist for Child O; or that police are warned to "believe nobody" at the outset of a police investigation - these things can be checked and considered on their merits by listeners.
If Davies or Watts were saying, trust me bro, Hughes is a bad'un and asking us to take it on trust, I'd be less interested in what they had to say.
Davies seems to have been disciplined for a genuine data breach - and to have owned it. Watts has never been found at fault at all, so to drag an accusation up against him two decades later seems a bit low
But I'm not terribly interested in their characters, their motivations, their histories. I'm interested in what they have to say and then I may be interested in checking some of it further. Useful information comes from lots of sources, and on significant points, what Watts and Davies say seems securely grounded in fact. Neither is essential to the case for a miscarriage of justice, but their contributions have been interesting.
Have they made any points you found problematic?
