I am not surprised. There just wasn't enough hard evidence against Scott Peterson.
I wonder if we'll reach a point where there is enough "science" and enough legal muscle for hire, that it becomes impossible to prove anything, ever. What then?
I was watching a DVD of a really funny comedian (Ron White) from Texas over the weekend. He said that Texas is trying to pass a law that says if three credible witnesses see you murder someone you go straight to the front of the line to be executed. No hanging around on death row. He said that while other states are trying to abolish the death penalty, Texas is creating an express lane. Texas is saying "If you want to kill someone, don't do it in Texas. Do it in California. They don't give a s%^&."
