Perhpas, but think of all we know about casey stealing from her parents, casey racing her father so he can't get to the trunk of the car on the 24th, how casey hid Caylee's whereabouts from her mother for a month, by telling her Caylee was busy or with the sitter, or there ahd been a car accident with Zanny, etc., so Caylee would not come to the phone or the could not come home yet, the July 3, 2008 Myspace from Cindy, why and where casey was eventually tracked down on the 15th of July, the smell of the trunk (It smells like there has benn a dead body in the damn car -CA), the smell of the trunk (the smell in the car washed over you like a wave - LA), the smell of trunk (is of decomp, it was so strong I could barely drive the car home, I'm bothered by that smell -GA), the suspicion of GA when he retrieved the car (I thought, don't let it be my Caylee), casey's phone calls to CA and LA from jail, the jailhouse visits, ruling out who may have made computer searches for chloroform, missing children, inhalation and death - ALL of this is hearsay unless the Anthony's testify. If they testify and vary from what they said before, they can be impeached. So, if they plead the fifth, it will be EXTREMELY HARD to get much of that evidence in.
