I think part of the problem is lack of prirotization within children's services as to which cases they are going to take on, which ones they should start care proceedings for.
For example, Coventry social services were roundly criticized by a judge for wasting hundreds of thousands of pounds in legal costs chasing a family with very flimsy reasons. I'm sure that at the same time in Coventry there were many children in dire need of quality social work whose needs could have been met if those funds had been properly allocated and someone had advised Coventry that they needed to prioritize their resources.
I have a good friend, ironically herself an experienced barrister who specializes in family public law, who has been forced to leave the country due to children's services. In the country she moved to, it was found that her dd needed therapeutic psychiatric care and is currently in a children's psychiatric hospital and that absolutely the worst thing for this child would have been to have removed her from her mother - yet this was exactly what children's services in the uk wanted to do. The social workers where she is, even after seeing all the material which was sent from the UK, cant believe that social workers in uk were applying to take her dd into care (and they got the order as well in her absence).
My friend was terrified at the idea of her vulnerable child going into foster care with god knows who, she was terrified her dd would commit suicide as she had spoke of it before. Childrens services have wasted thousands in legal costs in her case, doing more harm than good and meaning that chikdren who truly needed their support were going without. If she'd have gone into care, she'd have taken a 'spot' in a foster home from another child or gone to a ridiculously expensive care home when what this child needed was therapeutic psychiatric care.
Hopefully, the social services won't pursue her abroad, other than contacting social services in the country she's in which they have done and which is completely fine of course, but they may petition the courts abroad for the return of the children. That would be a disgraceful use of public funds and she may go to the papers at that point (who have said they are very interested but she hasn't until now to respect her dd's privacy).
There needs to be more accountability in the system rather than just pleading 'damned if you do, damned if you dont'. It's not that simple and when you have courts which look at a balance of probabilities rather than beyond reasonab,e doubt, the margin of error becomes much much greater.
