What would George and Cyndi Anthony do if Casey got off? How would they expect to lead/live their lives?

Casey would want her old room back. She's not going to tell her mother when she gets pregnant from now on! She will volunteer to pack up Caylee's stuff and donate it to Good Riddance oops I mean Goodwill. She will be the star at all the pool parties. She can show them where she held Caylee under the water when she accidentally drowned. If she's free, she can change the story when ever she wants. That's the beauty of it.
