All this nonesense about so-called 'baby snatching' is distracting from the main issue of whether the CS was warranted.
As I said upthread, I think this course of action was taken because the woman was
a visitor (which made treating her in the community within the UK, impossible as she had no fixed abode)
had long-standing MH issues
was probably beyond the safe travel period in her pregannacy that would enable her to be returned to Italy
had need of medication that they were unwilling to administer to a pregnant woman
was of no interest to the Italian authorities.
For these collective reasons I believe the decision was taken to perform the CS and return the woman to Italy. They probably expected no fuss whatsoever from the woman and never expected the case to feature prominently in the UK Press.
I believe it was just a 'take immediate action and sweep the whole mess under the carpet as quickly and cheaply as possible' job that unfortunately has attracted some publicity.
It seems that all the decison-making was done in a very short period of time and nothing like the months / years of assessment etc we have been told is attempted before a child is placed for adoption.
She could have stayed in the UK while her fitness to mother the child was assessed.
But they didn't do that as they'd probably jumped to the conculsion that she'd already had to forfeit the care of her other 2 children so consequently couldn't be a fit parent to this one either.
The child could have been returned to Italy in the care of the Italian authorities - just because they said they didn't want to take the child doesn't mean it shouldn't have been returned to the country where its mother (and siblings) were naturally inhabiting.
Instead the child remained in the UK care system - by defualt rather than by design.
I just think that they were unwilling to expend much money or effort in this case and hoped to 'do minimum' and expected the case would never be subject to scutiny.
Looks like they got it wrong.
