Baez never said that it would not be in Casey's favor to have Caylee found. He did say something about it would not be in her best interests to tell her story, (I am assuming he meant what happened to Caylee,) but that was several months ago, when they were still saying Caylee was alive.
Baez might have wanted the PI's to videotape that area to prove Caylee's remains were NOT there. But I doubt seriously that he was told by Casey where the remains were and then told the PI's. Remember, the PI's did not work for Baez in Nov., they worked for the Anthonys.
I do not believe that the Anthonys... any of them... knew where Caylee's body was all this time and did nothing about it. If anything they would have gone and retrieved her in the dead of night and buried her in private. There is no way in the world Cindy or George would have let that child's body lay out there in the woods and rot for months... not even to protect Casey. I jut don't buy that at all.
