No expert here on body language, just pursuing a thought to a logical conclusion. Body language is hugely automatic. It seems to me that all types of NONverbal language would be the most honest way of conveying what is actually happening inside you.
Following that, we are getting quite reliable information about how Casey's mind works just by watching her face. I feel OK taking her at face value.
It's obvious she does not respond in a conventional way. Her insides operate several steps to the "side". What matters to most people (we take it for granted IOW) does not register on ICA's radar.
I don't think ICA can help it. This was the (very personal) conclusion I reached about my exhusband who is sociopathic. The world impacted him in a different way than it does "normal" people. And I was the last to know. Where I saw companionship, he saw an opportunity to exploit. I don't believe he decided to just BE the way he is. I think his ability to process cause and effect is at about the 18 month old level. I really mean this.
An adult with an 18 month old's capacity to understand cause and effect is going to do what ICA did, what Scott Peterson did, and what my exhusband might have done had I stuck around for any more.
My grandson is 2 years old, and the utter blank look on his face when I am explaining why he must not squeeze the ducklings is understandable (albeit alarming, for the sake of loose ducklings) because he is developmentally incapable of being anything BUT hedonistic. The look on his face when he reached out to do some squeezing was . . . well, evil glee. Pure delight in his power to make something squeak and make Grandma and Mommy come running and emoting
.
My exhusband used to toy with me like that, and I swear he'd get the same look on his face.
Lookit what *I* can make her do.
I spent seven years (I loved him deeply) EXPLAINING, re-explaining, trying to educate this oblivious man on how to BE NICE to me, how beneficial for him it was to be polite, to speak directly about his needs rather than bully me or manipulate me. I was SO willing to meet his needs, I loved him.
He could not trust me (or anyone). I was devoted and loyal to him 100% until the day I turned him into the cops. I never shunned him when he wanted to "talk" or apologize. I was THERE for him. But he did not trust me because he could not CONNECT to me (or anyone). I proved myself trustworthy over and over and over again, in spite of some very abusive treatment by him. I did not desert him (until I finally did), I stood by him, supported him, accommodated him into depths few codependents are willing to go. And no matter what, he responded to me as if I were his enemy. As if my intention was to destroy him.
Sociopaths don't rely on facts and experience to understand reality. They rely upon WHAT THEY WANT (like an 18 month old) to dictate reality. Everything else flies right over their heads. Thus, the sullen or bored stare of ICA when they aren't talking about HER.
In ICA's world, no one else is real but HER. This isn't "evil", this is a developmental arrest in TODDLERHOOD. A toddler personality in an adult body is an imminent danger to others.
Depending upon the temperament of the arrested person, you can be ripped of for your retirement/savings/homes/assets (like I was) or killed. "You" do not exist as an individual in your own right. You are either a means to an end or an inconvenience that the sociopathic person feels entitled to deal with.
Feeling actual horror at the heartbreaking evidence of what happened to Caylee's precious little body is . . . irrelevant. And boring. What does it have to do with ICA, getting her out of jail and on with her La Bella Vita?
