Turns out that the Swedish passion for making list about people based on their ethnicity wasn't limited to just the Roma. They also had lists about Finns. (Not that suprising since we are basically the Mexicans of nordic countries, when we have had poor economy we skip the border or swim across the pond to Sweden in search of jobs.)
I'm guessing that if people really start digging up there will be way more of these lists and this is not the work of some random officers, this has been part of their culture in the Swedish police force.
