The guilt/innocence phase was over the moment the jury's verdict was read. It is then the responsibility of the defense to show actual innocence. 100%, without a doubt, innocence. There is no burden of proof on the prosecution at this point.
Well now, I'm not Merikan, so I'll defer to your knowledge of the US justice system. However if this is true, then it is
extraordinarily unjust. I'm no fan of the record of British justice, but this is certainly not the law on this side of the pond.
The burden of proof is
always on the prosecution. An absolutely valid ground of appeal is that the prosecution did not in fact prove its case, and that the jury's verdict was unsound. Take Sion Jenkins again as an example. A trial, two appeals and two re-trials. It was never proved 100% that he was innocent, it just took that long to get the system to acknowledge that the evidence against him had never been sufficient to support the conviction in the first place.
There are all sorts of reasons for a mistaken or unsound verdict in an original trial. This should not, and does not in any legislation I'm aware of, turn the burden of proof instantly on the defence. And I'll be blunt and say I don't believe you, and I don't believe that is the legal position in the USA either. Maybe TrainWreck or Loss Leader or another legal eagle will come to this thread and enlighten us for sure.
I mention this in particular because in another active thread another poster is making the bold claim that the degree of protection of the accused from a wrongful conviction is stronger in the USA than anywhere else. Whether or not this is factually true, it's inconceivable that anyone could make such a claim for a legislature where a conviction automatically turns the burden of proof on the defence.
So no, I flat-out don't believe you. And I spent some time yesterday listening to a senior lawyer arguing a legal case that a conviction was unsound (in Scots Law), not because he had found some magic incontrovertible proof of innocence, but because the evidence presented had been erroneously interpreted by the original trial court.
I do not believe you that it is different in the USA.
