I think 20 years isn't enough. I would have liked to see her get life. I saw the clip of when they read the verdict in court...she didn't blink, move, or show any emotion at all. I think that said alot about her "mental" state and the fact that she knew what she did and wasn't sorry for doing it. Should have been a life sentence but I'm sure the inmates will give her a warm welcome regardless
She did cry a little bit after the verdict was read but it was just for a show at that point.
