The home education aspect is, I think, a little bit of a red herring. In this case, the local education authority were involved, but didn't handle that efficiently. From the link I posted, the relevant paragraphs are 99 to 103. If the law were to be changed and all HE families were required to have the equivalent of an Ofsted inspection, that would result in an increase in the cost burden of the local authority while there's no guarantee that abuse cases of this kind would be picked up anyway. As a contrast, there are cases of child abuse that get missed, even when children are attending school regularly.
There were reports to social services from other sources - one was the family's previous GP, and another was from a GP who lived next door to the family. But somebody who can emotionally manipulate her daughter into inseminating herself is likely to be very good at deflecting social workers.
Apologies if this seems to be criticising your views, Fellatio, I don't mean to do that, just that, as Mumfun says: I just sometimes don't know how these people can be stopped. And the sad fact is that no matter what powers (and money) are given to local education departments or to social services departments, there are still going to be abuse cases that get missed. It's a deeply distressing situation.
From one of the other judgments, I gather that the criminal case took place some time in August last year. So that means that the woman will likely be free, but on licence, in just under two years' time. That's not really long enough for the two elder daughters, who are probably suffering from something like the Stockholm Syndrome, to gain a sense of their own self. I do hope that one of the conditions applied to her licence is that she has no contact with her children.
AIBU to hope that this woman gets some sense drummed into her while she's in prison?
