I'm sorry but your post is complete nonsense. All made up to push a specific agenda.
It's very, very worrying how many different usernames have popped up lately pushing or hinting at the Lucy Letby Truther conspiracy theory.
People on the ward had concerns that Letby was hurting and killing babies, and were concerned about her strange and intrusive behaviour towards the grieving parents.
The death rate started to soar, and some of these were stable babies.
Letby's own behaviour caused people to suspect that she was the murdered. For some of them, there's medical proof they were intentionally poisoned (something even Letby herself testified to in court, and both the medical evidence and Letby's testimony proved the specific details can't physically have happened without intentional poisoning). Other babies had horrendous physical damage. Only Letby was around for all those babies.
There really is no doubt at all that she's guilty, she left confession notes for God's sake!
I've been researching the Letby Truther Movement, and it is led by two individuals who seem very unwell and biased. Richard Gill has no medical background and has made some horrific comments about the babies and their families (like saying it was no big deal because the babies would have died anyway). Gill cannot legally enter the UK (he lives in Holland) because he's been told he'll be arrested for contempt of court if he does, due to his illegal actions over this case.
The woman who set up the "Science on Trial" Lucy Letby fansite (which multiple usernames keep pushing here on Mumsnet) has a long history of harassment and trolling, has been banned by many True Crime forums for repeated harassment and sock puppeting over her obsession with Letby conspiracy theories, and was declared mentally incompetent by a court - her court records are online and very very revealing. Both she and Gill are very good at writing extremely long posts that weaponise medical jargon to try to blind people with science, but without saying anything of real value. And both of them do the "maybe there's been a miscarriage of justice just playing devil's advocate" hinty thing, rather than going full Alex Jones.
There is no capacity for any miscarriage of justice here. There's medical evidence, and she left confession notes. If she wasn't a pretty middle class white girl no one would even be questioning her guilt.
And I think race does play a part in it, because these kinds of conspiracy theories are strongly associated with the right wing (eg Sandy Hook Truther Movement) and they always, without exception, focus on inventing conspiracy theories claiming white people have been scapegoated and framed for serious crimes. I looked at a Daily Mail article about Lucy Letby and all the top comments were defending her and pushing conspiracy theories that she'd been framed. Would Daily Mail commentators be defending her so hard if she wasn't white British and middle clas? Look at Alex Jones, he weaponsed racial hate to create a conspiracy theory that the Sandy Hook massacre was faked and the grieving parents all paid actors, and that was all wrapped up in American right wing racial political ideologies around terrorism and race.
Obviously this is different, and Britain is very different from America, but I see a lot of similarities between the Letby Truther Movement and the far right conspiracy theories - the fact the Letby Truther movement is only really taking hold on sites and forums known to be right wing is pretty significant.
