take responsibility!

A terrible item in the news. A baby girl (less than 2 months old) was killed by her father who had systematically physically and sexually abused her. Over 30 professionals had seen the baby and some had flagged concerns about abuse\potential abuse but no-one had actually done anything.
An enquiry has determined that no-one is to blame for the oversight as it was an failure in the system.

What the hell do we pay doctors, nurses, social workers for, the system isn't to blame it's the people in that system. Why have people stopped taking responsibility?
