I have to disagree with you here, I do not think most jurors have already connected the dots. The jurors are not allowed to talk with anyone about the case, nor are they allowed to study photos, documents, etc. They also are not allowed to watch all the hype by the media. That leaves them with their own thoughts on what has been said, and what they have seen at trial.
They have what possibly may be KC's life in their hands. I think they will reserve judgement not only until the DT finishes their case, but until the rebuttals and closing statements are finished, and have spent time deliberating with the other jurors. After all that, they will ultimately decide whether or not they want to convict KC of murder, with the ultimate penalty attached.
I realize it is possible that some of the jurors may have already made up their mind, but whether they have made up their mind as to whether she is guilty or not is another question. Dr. Spitz's testimony may have been enough to convince one juror that KC is not guilty. None of us know what is going through the minds of these jurors. The media doesn't know either, all they can do is speculate and their speculation is geared towards ratings. So, really all we can do is speculate as well.
I will totally agree with you though, that it is very important that the state clear up these things, if they can, because to me these things definately need cleared up.
As always my entire post is my opinion only.
