I withdraw the theory that Casey was home at 4pm -- I understand she was at Tony's and arrived home much later. It seems as though George and Cindy went into overdrive -- by instinct or design -- soon after learning that Caylee was in trouble. I've listened to the 911 calls and as best as I can tried to listen closly to the background. When Cindy threatens to go to child services/court and says "if you want to play that game" Casey says "I don't want to play that game". During the 3rd frantic call -- when Cindy is asked Caylee's skin color -- you can hear Casey say something in the background (probablys sarcastic comment). Casey also speaks to George, while Cindy is spewing information, Casey tries to intervene, to get ahead of Cindy in telling the story -in her own, calm tone. (Caylee's is missing, she's with the babysitter). When Cindy asks Casey to get on the phone with police -- I think Casey says "ok give me the phone, let me talk to them". And when the dispatcher asks her what's going on over there -- Casey is like -- what? excuse me? -- as if she can't imagine what it is that the dispatcher could possibly be talking about. She's amazingly calm -- like -- why does everybody have their panties in a bunch,chill folks.
