Knittedbreast - if you really believe that children are removed, on a whim, from parents who have done nothing to raise concerns then you are absolutely, massively mistaken. IMO the cases where mistakes are made (and I'm talking generally here, I have specific examples but obviously can't discuss them in detail) are where the thresholds are different from area to area, or SW to SW, and when a parent may have been able to manage with the right support and doesn't get it
Now people are talking about lack of P&B placements - I have known families go to P&B placements 100s of miles away because that's where the space was, not that they refused to pay for one. But it's a reality that budgets are far too small - that's not SWs' faults, or SS depts - that's central govt and it's getting worse.
I have never ever known a family get to CP proceedings without real, huge concerns. There have been cases where the assessments have been over zealous, true - but it always gets stopped before CP proceedings. I have only ever been involved in one case where I felt the child should have been left with mother and wasn't - but it was incredibly borderline and my views were based mainly on the age of the child. Had it been a new baby at the time - maybe not. That child was returned after a period of time and £££££££££ invested in mother anyway.
Often the concerns are because the parent/s are very young, have experienced abuse themselves, and have no idea how to parent properly. They may love their DCs to the ends of the earth, but that doesn't mean they can parent them safely. That's a huge, sad and unavoidable fact. I'm often involved in supporting young parents through CP proceedings, and although I work for SS and have a duty of care to protect the children my emphasis is on supporting the parents and I have huge sympathy and empathy for them, but I can't pretend that all are good enough.
