I absolutely agree with you Jayla and you bring up some good points. Not wanting to put words in your mouth (in case you believe something different to what I do) here's the issue I see.
I believe ICA is a sociopath. She does not have the basis of original feelings the rest of us who are not sociopaths do. I'm not saying she doesn't have feelings, but her feelings are inappropriate to the rest of us.
So ICA has a real challenge at trial. She has to fake her feelings, she is acting feelings that she thinks she should have, and try to shut down the feelings she is actually having. Most of the time in the hearings we've seen, like you've said, she has actually sat there showing little or no feelings, or else she is twitching, stroking, constantly grooming, and frantically writing or watching the documents her lawyers have in front of them.
So how will the jury view her? Well she sure won't look "normal"! She'll show anger when she should be extremely distressed, she'll look bored when she should be horrified when the SA discuss how Caylee died, she will laugh inappropriately, and obviously shed a few fake tears when her lawyers are talking about her, not Caylee.
We know ICA has a very short attention span, and I don't believe all the pre-trial coaching will show a consistent change of behavior. She'll remember how she is supposed to be for a few minutes, then I think she'll revert back to her very unlikable self. In other words, I think ICA will present a "self" a jury will believe could - no did - murder her own child.
I almost feel sorry for the Defense. Not.
