I'm not going to spend a lot of time on the subject, but I'm surprised by the hysteria concerning the acquittal of Casey Anthony.
Ms Anthony didn't "aquitt" herself well, she's obviously a serial liar, but I also felt, from what I saw of the case, that the case against her was weaker than the media portrayed it as. Just being dishonest and a slimeball doesn't make you a child murderer, and while there certainly were pieces of circumstantial evidence that made things look bad, you certainly can't convict someone of first degree murder on that basis.
Especially when such a verdict would likely result in an irrevocable execution.
Perhaps that was something running through the minds of the jury when they made their decision. If so, that'd be one of the few times the existence of the Death Penalty has served the cause of justice.
