ITA the state did not prove that FCA murdered Caylee. However, my understanding is that they were only required to eliminate reasonable doubt.
The fact is, an overwhelming majority of us who have followed the case very closely, examined all the available evidence (some of which was not presented in trial for various reasons), and gone over every possible permutation with fine toothed combs, agree that this person should have never been acquitted; that any doubt as to her hand in her daughter's death is one that defies common sense. Certainly the story that convinced the jury (versus the actual facts available), one that morphed over time and came out of the mouth of an inveterate liar was much more incredible and strained the boundaries of reason far more than the actual facts in evidence and the testimony of scores of credible witnesses to the contrary.
I doubt most of us feel that the state did less than its job in presenting the facts and that the only reason a more sensible verdict was not reached was due to the fact that a jury of 12 preferred a fantastical story without any discernible basis or proof over the multitude of facts in evidence that created a strong circumstantial case against the defendant. The disconnect for most of us is that a jury would immediately take the word of a proven liar and thief, with a story that does not logistically compute and actually contradicts the facts in evidence (particularly her version of the events on the morning of June 16 which are easily contradicted by phone and computer records), and without so much as even reviewing those presented facts, return a verdict in a way that was so hasty as to make a mockery of the entire judicial process. I won't even get started on all of the ways the defense team shamelessly manipulated the media and the court for fun and profit and wasted taxpayer time and money with unethical and unprofessional behavior and accusations.
And I won't bother to compare how many many murderers have been convicted on much less evidence and without a body simply because a jury was willing to admit the available evidence suggested a preponderance of guilt.
If local defense attorneys in Orlando are gloating it is probably because their jobs have been made easier by Barnum's old saying "there's a sucker born every minute" proving true in this case.
