This woman is a liar and a cruel calculating murderer. She plays all innocent while she tries to influence the jury about what a poor unloved life she has lived.
Meanwhile her lawyer and the Moguls are all sitting waiting to get their greedy hands on a book deal or the film rights to this horror story.
She is playing it for all it is worth. Even if she gets the death penalty, the poor tax payer will pay to keep her for 10 or so years. The taxpayer will also pay for her lawyers to submit appeal after appeal on her behalf.
