he thought...

I had no opinion of Ashton until I saw for myself the level of arrogance and lack of respect he has for his job and society in general. He thought public outrage and character assassination would win the case for him. He was, and still is, $$$ banking $$$ on the public to be stupid enough to continue believing his theory when it was debunked by Dr. Spitz in court. I notice that was conveniently left out of his movie:

I don't think he ever cared about Caylee, or about the truth at all. He saw this case as an opportunity to become famous and cash in on a dysfunctional family's problems. He got a book deal, paid interviews, and a movie now. He's treated almost godlike by the very people he's duped into believing his disproven theory. Behind their back, he's laughed himself all the way to the bank.

He should be ashamed of himself, but that would require him to have a conscience.

That's why he lost. Ashton thought the case was a slam dunk but he was wrong. What prosecutor writes a book before the trial was even finished. The day Casey was sentenced Ashton was hawking his new book instead of being in court with the rest of his team.
