After every case like this, the number of children taken into care goes up. For some it will be the right decision, but for others it will be a "better safe than sorry" exercise because of the lack of resources and the bureaucracy of allocation. There will be a recruitment campaign for foster carers, and every professional dealing with children will be on high alert, partly in the best interests of children, partly as an arse covering exercise.
Right now I do think the home schooling aspect is being over-egged but to be blunt it's a crowd pleaser, it selects a group of people that are different from the majority and gives people a sense that "something will be done".
The main drivers of child abuse and neglect are poverty and addiction, which are rarely properly addressed at state level. Yes, there are depraved psychopaths out there, but as can be seen, they manage to fly under the radar regardless of systems, processes and oversight - although in the case that is prompting the current threads, it's blatantly obvious it's a whole series of system failures with home education being a red herring, and allowing certain agencies and the judiciary off the hook.
Most families have plenty of oversight in a child's early years, and most families are not abusive. Losing the SureStart initiative has been mentioned as a turning point in declining outcomes for vulnerable children.
I don't think that assuming all children are always at risk and treating families accordingly will identify those genuinely abused, and will further erode what little trust there is in the authorities.
There are posts regularly on here with parents at their wits end appealing for help when things are going wrong, and they describe being passed like a hot potato from one agency to another while risks do increase. See also the education system and all the bureaucracy involved when trying to get SEND children into school, leaving many parents feeling home education is the only option.
No matter which way we slice it, the breakdown of families and communities is being accelerated by the pressures of modern life and financial deprivation, and children suffer in a myriad of ways.
Increasing monitoring without addressing the issues contributing to the reasons why children are being harmed is like sticking a band aid on an arterial spurt.
