It’s hard to recognise Sweden from the news reports we’re reading nowadays. Yesterday, a 15-year-old at an immigration centre stabbed and killed one of its female employees in Mölndal, near Gothenburg. It’s the kind of story that shakes the country to its core. Sweden has taken a staggering number of unaccompanied children – some 20,000 in the past four months – so the government has to act in loco parentis. To keep them out of trouble, as well as educate and accommodate then. It’s a very tough ask, a job that many Swedes fear is simply beyond the competence of government. In such circumstances, appalling things can happen.
