I think everyone realizes that it is indeed the defense's job to raise doubt. While there may be some that will say that what we know at this very moment might not be enough to convict Casey (and for the record, I personally do not believe this), there are VERY FEW who actually believe Caylee is alive.
They can spout anything they'd like, but not many will change their opinion based on Baez' leaks and/or propaganda.
IMO, having a gag in place will not effect many opinions. Casey Anthony is the biggest liar on the face of the planet; or at least the biggest liar I have ever heard of. She, of her own free will, did not contact authorities when her daughter was missing. She's the one who proclaimed there was a real life Zanny the nanny, WITHOUT a single shred of evidence to show the woman even exists; aside from inside Casey's own imagination. Baez can say what he wants and it is his job and his duty to try and counter everything, but no amount of spewing on his part is ever going to change the facts.
EDIT: I see the quotes around this, so I assume they were Baez' own remarks when you said, "We are objected to the gag order at this time." Can someone help me out here? Is this even a grammatically correct statement?
