The second one has already been done. remember to turnabout beginnings? tbh everyone remembers the ending and not those details. that being said, the judge being the killer would actually make accusing the judge in jfa even better.
I thought that about the 3rd one too, but I think it might mean that the defendant actually did it but only in self defense? I'm not sure though. If it just means whoever the guilty party is only did it in self defense, than yes, that did already happen.
No for the third one I mean the defendant is the culprit and the verdict is self defense. In Samurai the defendant was innocent. Also for some reason I though Beginnings was called the Forgotten Turnabout. I’m an idiot. Remember Memories though.
