Not neuter. Streamline. Too many capital cases arrive at an execution verdict on sketchy evidence. One overriding independent review is all that is needed, to determine if there is any doubt about the verdict left. Much like what we have now, without the lower processes redundantly sucking up resources and throwing money away left and right.
So, if everyone was more competent, the process would be cheaper, and by making the process cheaper from the get go ... everyone will be more competent? Something about that math feels off.
