Casey Anthony was convicted of four counts of lying to the police. What kind of questions did she lie about? If they were questions about the whereabouts of her child and she lied then why? Obviously to cover up what she did to her. Jurors can’t find her not guilty of murder when they then convicted her of lying about what happened. It’s just not logical. No wonder they call it Flori-duh.
But what is "what she did to her"? That's what wasn't proven. Did Caylee die in an accident and Casey try to cover it up? Did Casey intentionally kill her daughter? Did Casey flip-out and kill Caylee in a fit of anger? Did Caylee drown and Casey agree to cover it up to protect someone else? The prosecution didn't prove *what* happened, so she can't be found guilty of even manslaughter.
