No kidding.  Courtney Saul drowned her new-born son in the bathroom sink because she had an examine and get probation.  Why not murder?  She purposely drowned her son with full knowledge and yet gets off with probation by telling a sad  and unsupported story of how hard it was and she didn't know the father etc. etc. etc. 
"An Alberta woman who admits to drowning her two young sons in her bathtub was found guilty today of manslaughter.
Justice Michelle Crighton rejected Friday a conviction on the more serious charge of second-degree murder. "I would describe her as being tormented by the death of her boys, but at the same time confused regarding her role in that," she said. McConnell killed her boys at the family home in Millet, Alta., as revenge against her husband."
Exactly why isn't this murder?  Well, the judge felt sorry for her and made up an excuse.  What would have happened if it was a dad killing the kids for revenge on his wife?
