Comment: If there's one good thing to say about Facebook, it's that it makes identifying the scum of the earth a lot easier.
In a case that has shocked France, the man reportedly admitted being violent towards the infant, who was taken to hospital where doctors diagnosed possible brain damage.
Police in the town of Tergnier in the Aisne department in Picardy, northern France, were alerted on Monday by one of the couple's friends who saw the child's picture on the father's Facebook account and was concerned at the baby's "abnormal appearance" and bruised face.
Officers summoned the mother for questioning. When she arrived detectives noted the infant's injuries were even worse than in the photograph and alerted the emergency services. The mother allegedly told detectives she was afraid to contact police for fear that her partner would leave her.
The father was arrested on Monday evening. Both parents have been formally put under investigation, the equivalent of being charged, for "violence against a minor causing permanent incapacity".
Comment: From the heights of political power to the lowest petty criminal and abusive parent, psychopathy makes its influence known. It's the reason why things that should be obvious to everyone - basic values like the fact that beating women and children is wrong - are not. Humanity is lost.
