For those who believe the system worked for Casey Anthony, did you believe it worked for OJ as well when...?

I believe both those outcomes were failures of the justice system. I'm still more inclined to believe OJ than I am to believe Casey Anthony. At least OJ had the decency to pretend to care. But I digress. The justice system is far from perfect,but what are the alternatives? Anarchy sounds pretty good to me right now.
