You really think Norway is going to stand up to and get involved with swedish CPS issues? It has to be really blatant for them to even consider that. And while the article presents it as quite blatant, I doubt it is that blatant. Shitty or not, there at least has to be some reason to justify taking the children from the father.Why flee to Poland when Norway's just next door?
The CPS's tend to have a lot of power, and it's going to lead to a lot of bad decisions, so they need to be under heavy scrutiny. But their work is also very difficult with a lot of lose/lose situations. And unsurprisingly when the CPS's methods get criticized in the media by families who has lost custody of children they seem to forget to mention whatever abuse or neglect they are accused of.
In any case putting children into families with such a different culture and religion is a huge ethical question in itself. I think it's fair to claim that if you reverse the issue there would have been lots of people lining up to call it racist. It certainly seems bad to put already very vulnerable children who's losing everything they know into an even more unfamiliar situation than needed. It could also be questioned if these are the people who should be brought up into what is a very separate subculture in the country.
But yeah, suspicious to how true this representation of the story is, but sadly wouldn't be too surprised if it's true either.
