From what I've heard, Sweden and Norway have a habit of forcefully putting immigrant kids into care for reasons which would be deemed unthinkable in many other countries (e.g., a single smack, of the kind which would be legal in England)
Am not saying that particular case of extreme lockdown was alright, but it doesn't mean the Swedish social services were fair and proportionate either. They are notoriously very heavy handed, and biased against immigrants.
