I don't understand why everyone seems to be so upset about LVD being declared incompetent. It doesn't mean anything. She will still sit in jail and she will still face her charges. Except NOW, they will treat her for whatever mental illness until she IS competent to stand trial, thereby removing any chance of a mistrial.
I have seen plenty of speculation here that there is something wrong with her, and has been for quite some time. I have even seen suggestions that she "faked" the mental illness test that CV had requested. So why the big deal? There IS something actually wrong with her. We all have seen it. Let them treat her. Because maybe, just maybe, when she becomes in her sane mind, she will realize the magnitude of her actions and will confess and give everyone the details needed to prosecute others.
