Casey Anthony was acquitted because the prosecution failed to prove their case and the jury properly did not send Anthony to jail and maybe a death sentence just because a mob of screaming women outside the courthouse wanted that.
In this case the jury system worked just fine.
The message to prosecutors here is not to bring charges against people until they have a solid case.
not to mention the junk science experts.
Exactly. Casey is guilty of crimes, but the prosecutor failed to prove murder. IIRC he did manage to prove several others.
It would be a hell of thing if people could be sent to prison or death just because a screaming mob demanded it.
