Here's the Oslo cops' response to that article on Oslo crime:
"The Oslo police has NOT lost our city. We are far from having an "apocalyptic level" of violence. This is true also for the vital city center district in Oslo called Grønland. Since 2011, the number of recorded robberies and rapes has declined by around 50 and 20 percent respectively for Grønland precinct. Oslo Police District is proud of the good work that our diverse staff provides to the people of Oslo. A good cooperation with civil society allows for this." @politietoslo, January 7, 2016
