I just wanted to point out something about the fact Kobe is now working for the defense. Just because he has been hired does not mean he will be on their side. Do you really believe he would lie or make up statements of evidence in order to help Casey?
This is a guy with a professional reputation and practice. He's not going to throw it away on any case for any amount of money. If he's unethical, he's ruined his career and livelyhood.
In all possibilities, what he uncovers about Casey may not even remotely agree with the way the defense is going. If he finds something that hurts the case, they will not use his testimony for sure.
By the defense hiring him, they have kept the prosecution from hiring Kobe to work for them in convicting Casey. It's a smart move on the defense's part to lock up Kobe regardless which way this case is heading.
We and Nancy too might not like the idea that he is working for the defense but we should consider the big picture of what is happening. Any of us, if necessary would want the best defense and tatics money could buy. Just my opinion but I think we need to look at this both ways.
