No she didn't. Greer made errors that, in any capital case, would have meant he was overturned. Why the state oredering the death of non criminals should be given less scrutiny by the appeals courts than capital murder cases is beyond me.
It is "beyond you" because you are accepting a distortion of what happened here combined with a misunderstanding of what the law is regarding such matters.
It will always be beyond those who believe this was a murder committed by a gigantic conspiracy.
However those who actually care about the law and know there was NO conspiracy gigantic or otherwise but just the ordinary court work done in the same way every day throughout the world find nothing here "beyond them." Except perhaps the actions of the Schindlers.
