It doesn't mention an immigrant rape crisis, and in fact gives an explanation for Sweden's high rape reporting rate:
"...
On the face of it, it would seem Sweden is a much more dangerous place than these other countries.
But that is a misconception, according to Klara Selin, a sociologist at the National Council for Crime Prevention in Stockholm. She says you cannot compare countries' records, because police procedures and legal definitions vary widely.
"In Sweden there has been this ambition explicitly to record every case of sexual violence separately, to make it visible in the statistics," she says.
"So, for instance, when a woman comes to the police and she says my husband or my fiance raped me almost every day during the last year, the police have to record each of these events, which might be more than 300 events. In many other countries it would just be one record - one victim, one type of crime, one record."
The thing is, the number of reported rapes has been going up in Sweden - it's almost trebled in just the last seven years. In 2003, about 2,200 offences were reported by the police, compared to nearly 6,000 in 2010.
So something's going on.
But Klara Selin says the statistics don't represent a major crime epidemic, rather a shift in attitudes. The public debate about this sort of crime in Sweden over the past two decades has had the effect of raising awareness, she says, and encouraging women to go to the police if they have been attacked."
