Lass and I disagree on just about everything, but on this she's spot on.
The mother was the one with the most responsibility, I'm aware that social services and other agencies did too, but this absolution of parents who fail to do even the most basic of parenting in the media and online really angers me.
Lucy had, at best, a dysfunctional family set up. Her mother denied issues to anyone who came to check on the child.
She was a baby, a little girl who nobody fucking protected, who was raped, repeatedly.
And her mother did nothing.
