This is a travesty, and the jury deliberations may not be straightforward. But I have faith every single juror is not going to acquit her of murder or at least aggravated manslaughter, even if one or some might. Worst case there will be a retrial. And the Anthony family can be investigated and charged with perjury and/or obstruction and/or evidence tampering before that retrial, and that will render their testimony completely useless in a second trial. And I hope they are prosecuted in such a way it makes them unable to profit from Caylee's death.
As the saying goes, you can fool all of the people some of the time, and some of the people all of the time, but you cannot fool all of the people all of the time.
Whether the Anthonys like it or not Caylee was not their property, they are not God, they do not get to propose and dispose. She was a citizen of the State of Florida with full legal and human rights, and they are answerable to higher courts than their family dining table.
