She's been ruined by this, but that doesn't mean she no longer has a right to rebuild her life. Somebody will profit off of Caylee's death (even more than those who already have...why aren'y you throwing Nancy Grace under the bus?), and if Casey can rebuild her life by telling her story, or signing off on the rights to the story she probably will.
At the end of the day, I don't know what kind of person she is. The evidence doesn't consistently support the most ardent conclusions voiced in this forum. While there are some questionable scenarios and some pretty ****ty actions, there are also 22.5 years of history which contradict everything that happened in those 31 days. So either something changed her, something snapped, or she put on a well-executed act for 22.5 years. I'm not a trained psychologist, therapist, or expert in human behavior, so I'm not going to run around screaming about how sure I am when I know I can't be.
