I don't think this is any case of post partum depression. KC is just pure evil. She isn't depressed. With PPD the woman usually can't even function. They aren't out partying and sleeping with men. I think the defense would have a hard time claiming KC had that. You can tell by looking at her that she is just a big psychopath. Never seen such vacant eyes.
There's evidence to support KC didn't start to act like this after Caylee was born..Many told LE she was a LIAR long before that day!
One even said she was a LIAR as a kid..You've heard the story about the dog & the neighbor?..SCARY!
