i'd find your faith in the system endearing if only it wasn't so arrogant. at the end norwegians and swedish are only human. they can get things wrong some times, you know...
Sure they get it wrong sometimes. But as I said do we really have the story here? It's sensitive information and also according to law the norwegian authority cannot openly discuss this case with the media.
All we got is some understandably angry parents who probably focus on some petty detail they thought got give them support in the media and from the public.
Here in Sweden we have had hundreds of very severe cases of abuse involving people from other countries that might have held their children away from school, prevented them certain medical care etc.
Parents in Scandinavia most certainly have more requirements then they would have in India for example but in Norway everyone that lives their is subject to norwegian law and not the law in their home-country.
They also get more support. Here in Sweden the parents get substantial tax free support for every child all the way until they are 16. Other types of support are also raised with every child if such support is needed (in case of low income which is common for immigrants) That makes sure the parents can afford clothes, a bed, food, medicine and all those things. But sadly some people that come here think that support is "free money" so they sometimes neglect their children, take it for themselves and their expenses or send it home or something.
Child protective services normally only get alerted if something has been wrong for quite some time. It's not like they drive up with a bus, abduct children and then laugh about it. It's a very severe action that takes very solid proof and multiple decision makers. It's not a thing taken lightly. It's easy to get that impression from the article that it was something stupid like authorities paid a surprise visit, saw they slept in the same bed and then decided to take the children. It's because we don't get the real story behind but only some ramblings from the parents
