How far does parental love go?

How delusional does one have to be to buy this whole Caylee Anthony story? I know she doesn't want to believe her granddaughter is cold and dead and buried, but man to go on national tv and share this? Are you kidding me? I mean at some point wouldn't you feel embarrassed? Is there some reason the cops don't round the whole lot of them up and charge them with obstructing a police investigation? God.
