I think you will find that many convicted criminal feels their conviction is unsafe.
"it's not me guv" is a cry often heard in gaols-to the extent that it can sometimes feel as if the whole prison estate contains more innocent people than a nunnery!
I think we have to accept that two juries found Letby guilty and, not only that, a panel of judges decided that she had no grounds for appeal.
She has has a a pretty big bite of the judicial cherry. She is guilty but, in just the same way, that every death row inmate in America has a merry band of people yelling that they are innocent, so too has this convicted serial baby murderer gathered her own gang of misguided groupies.
She has been through the legal system-twice- she has been refused leave to appeal and yet that is still not good enough for a bunch of armchair judicial experts.
She will rot in jail and despite a minority of very loud voices, that is exactly what should happen.
In a year or two, the circus will have moved on. It is distasteful and the sooner they do, the better.
