The YouTube video released by Casey Anthony gives me additional confidence that my insights into her, psychologically, have been accurate. Most notable about Ms. Anthony’s statements is the one in which she speaks of finally owning something she need not give back to anyone—a computer, a camera and a cell phone.

These, of course, were the treasured possessions through which she interacted with others before her murder trial. Casey Anthony used MySpace and Facebook as ways to present a false self—a synthesized, sterile “profile”—to her friends and lovers.

Now, possessed once again of the essential tools to reach out without ever revealing her true self, she has added YouTube to her social networking arsenal—a mode of communication that resembles nothing so much as a suit of psychological armor.

Nothing in the YouTube video reveals anything about Ms. Anthony’s internal emotions or thoughts. There isn’t even a nod to the importance of such things. Never does she mention struggling with the loss of her daughter. Never does she mention fearing a life in jail, or execution.

What seems to matter to her is that she can keep her computer, camera and cell phone when she leaves the secret location where she is now living. They define her. She would never risk a life lived without new media to hide behind.

Her daughter, of course, was never hers—not really. From the moment Caylee Anthony was delivered into the world, Casey alleged that she was commandeered by her grandmother, Cindy Anthony. And Casey, of course, was never her own person, either.

Despite the release of this tape, Ms. Anthony remains to all, including herself, a stranger. She is immediately and palpably at home in front of a camera because she has been acting her whole life. The audience was, at the beginning of her life, parents who neither nurtured nor knew her in any genuine way, whatsoever, but who she learned very quickly she needed to satisfy, in one way or another.

Casey is a study in light and shadows. For now, the light is fabricated. The shadows are all too real. And her only hope for salvation is in keeping her eyes open and looking at the dark realities of her early development long enough to stop running from them, to grieve them and, perhaps miraculously, to overcome them.

Ms. Anthony tells us that she has acquired a dog, then states that the animal is as much or more of a family than she has ever had. In my view, she is correct, and that single statement about her new dog may be the only one that offers any insight into her.

Casey Anthony, the most notorious woman in the world, looks at ease. Think about how estranged from reality and from oneself a person would have to be for that dichotomy to exist.
