I want to understand what is going on with Casey Anthony and her family, and I know that several readers have written, voicing similar interests. So, I've sent an invitation to an expert in narcissism and asked for a guest post.
Hopefully, we'll have that input by Friday evening - if not, I'll send out another invite to an expert in narcissism or sociopathy, etc. and (fingers crossed) either way, we'll have an expert giving us details on this issue.
Personally, I pondered on this issue a couple of years back, as fodder for character studies in my personal writing and I posted about this at my fiction writing blog (here).
For me, I don't believe that Casey can be considered without looking at her family, particularly her mother. There's something sad and bad about their relationship - but I'll wait to hear what the psychologist has to reveal about all this.
Reading one reader's comment here - Anonymous on June 5th to Who Is Jose Baez? post - I think she may know more than the rest of us about the family dynamic in that house, e.g., that Casey became a liar as a means of escaping the overwhelming power and control of her mother. That makes sense to me.
One other thing: I wish that I could look at Casey Anthony and consider the possibility of a mother killing her child as a bizarre, unique instance - but I can't. One of the biggest shocks that I had when I worked the local CPS Docket was the parents, particularly the mothers. There were some that were blind to their children, they did not care. I learned that a maternal instinct is not a given in humans. Some chose drugs, true. Some, however, just did not love those babies - and "blind" is the closest I can get right now to describing their lack of perception.
