Yeah, he probably did it.  You can feel in in your gut, right?  That's pretty much what the jury said when it convicted Scott Peterson of the murder of his wife, Laci in 2004.  But is demeanor evidence really evidence?  And does it prove guilt beyond reasonable doubt?  In Part 2 of her series featuring three men named Peterson who were each convicted of murdering their spouses, Melissa takes an honest poke at how Scott Peterson - who by all accounts is a no-good, cheating, lying rounder, got convicted of first degree murder with special circumstances based on little more than the fact that the jury didn't like him.  Whether you think he did it or not, the key question of guilt beyond reasonable doubt was thrown to the wind in this case, and Melissa asks:  Is that the kind of judicial system we really want?  A truly unique case gets a fresh look and a critical view through Melissa's uniquely focused lens.
