Surely the real issue is not about a load of navel gazing MNers who are competitively sadding or competitively hard-assing, it's about Haringey SS and, at a broader level, British society where we not only have this case but also Shannon Matthews on the same news bulletin
Wake up: it's not about you and your feelings but it is about you and your society.
Far more productive to ponder how you can make minor changes in how you live your life/ bring up your kids to make something like this less likely to re-occur
For example: if you think a child is at risk, report it and follow up that report. Don't "not like to interfere" but post about it on MN and so vicariously do something.
Help your child to read/ support teachers/ schools rather than think they "do enough in school anyway and don't need to do any homework" and then wonder why they leave school disillusioned, under-qualified and incapable of reasonable parenting.
Don't waste time apportioning blame: that's the job of the authorities.
I lived in Haringey for years and it was extraordinary how shoddy so much of it was. My friend is a parent helper in a Haringey school and, while well intentioned and well educated, she has no special training but is helping a child with Downs: there is proper help available within the school (including the teacher) but because this child is pleasant and easy and "won't come to much" she has been given my friend rather than getting extra help. Her parents don't demand any more so that's it: the parents and the school know what's best!
And no, I've never voted Tory before anyone goes down that line
