Be gentle, this is the first thread I've started here. My question is, why are they offering CA immunity? I know LE just wants to find Caylee's body and give that baby some closure, but what advantage is it to Casey to go ahead and take that deal? I read that they can't use her words to prosecute her, but with all the other evidence and then you add finding Caylee's body, they've got their case and no longer need her confessions anyway. Is it because they really don't have that solid a case against her after all and they need this to "seal the deal" to keep her from getting off? Someone please help me understand why they think Casey would help them now just because they offer her "limited immunity"? It's so hard to decipher what is media spin vs facts lately.
