I think it is important to find out what went wrong so that it can be prevented. Having read an article in the Telegraph today it seems that there were significant failings by SS. The judge even condemned their lack of action and yet as usual SS have closed ranks and no explanation is forthcoming. There are comparisons being drawn with the Victoria Climbe case as well.
Personally I am terrified of having dealings with SS. Not because I have anything to hide but because there seems to be rampant inverse snobbery in SS dealings with white, middle class parents. I am not saying that this is the case, just my impression.
I also think that we are all so scared of this sort of thing happening to our own children that threads like this are almost a cathartic experience. It is human nature to talk about our fears.
