I just believe that someone bought the DT mitigation. In retrospect, I think they played that very well. I don't think that the difference between mental illness and BPD was explained enough. You have to admit that CKja's little show was nuts. The things she said, book club comes to mind. Someone could have thought she was mentally ill, almost child like. That and no witnesses, especially her family appeared to be neglect. We all know better but they did not. They really did not get to see the REAL JA as we have.
Someone could not go with DP for a mentally ill, abandoned person. I cannot fault them for that, that was what was presented to them and they bought it. (I only think there were 1 maybe 2)
IMO, they followed the law. Not their fault that the DT was very underhanded and lied just as well as their client. Something needs to be done about that!
