There is no need for the snippy tone, Phaedra.
There is a difference between legal and moral responsibility. Even if the court had decided the mother was not culpable legally, many would consider her at least partially responsible from a moral standpoint. Likewise, though she was found guilty that doesn't mean she bears all the moral responsibility some feel a guilty verdict implies.
We don't know if any of the points I raised were raised by the defence. Therefore I don't think we can assume anything about how the jury reached its verdict, or about her degree of responsibility.
However, the dynamics of abusive relationships in general are known to have a serious effect on people involved in them. If the defence didn't bring this body of knowledge to bear on its presentation of her case then they were remiss. If they did and the jury dismissed them then perhaps there were cultural factors at play that made it hard for them to understand the position of a victim and weigh it properly.
There is no gain for the public interest in this guilty verdict.
Women in abusive relationships who suspect their partners are abusing their children are going to be frightened to report it as they will fear jail. Men who are abusing children will find it easier to scare the mothers into silence as they will say 'you knew this was happening, and you went along with it,' or 'I will tell the police you knew' -- a man who knows the prosecution has a good case against him has nothing to lose by bullying his partner like this, and actually has something to gain, namely time to continue the abuse, plus the gratification of seeing the effect of his words. And both women and men see a case where a woman was dominated by her partner not believed in court.
This is also incredibly disheartening for women who want to divorce abusive men but who are afraid of the spectre of visitation where the children are left completely defenceless against their ex. The bar of proof of abuse is set astronomically high in many places for women who want to prevent an abusive partner from contact or even unsupervised contact with children. Many societies have as one of their guiding myths that children without a father in their lives will turn out terribly, and that single mothers are not capable of ever being good enough parents or good enough influences on their own to bring up children. Men would have to actually murder one of the children to be barred from normal visitation -- every other weekend with maybe a weekday evening thrown in.
