So, how is you knowing going to change anything? You going to bring her back? You going to have people arrested for murder? Have people arrested for abuse? Seriously, how is you knowing going to change one bit of it? I'm well aware I'm not the only person who has lost someone close to me. Happens everyday, doesn't it? That's why I am all for keeping private things private. There's nothing to be learned of value, here. Not all cases are the same. If they were, perhaps. But they're not. Personally, were I her, I would have been immensley grateful to have the plug pulled day one they knew I was in that shape, but that's me.
So, what benefit is there for you to personally have information as to whether she was brain damaged to "x" degree or not? And, can that even be totally determined by a post mortum?
Once again, you want to know so you can know. There's nothing you can do about it, which doesn't give YOUR high horse knowledge any value, does it?
