How to tell which groups are responsible for crimes in Sweden?

Two boys were robbed of mobile phones and money in their own home. In an article reporting about the crime, in http://www.hd.se/, one could read that the perpertrators spoke Swedish without an accent. The only time media report more than clothing is when the perpertrators are Swedish. What can you learn from this? When it doesn't clearly say that the perpertrators are Swedish, they aren't. And because it's seldom one reads about Swedes committing crime, one has to asume that it's immigrants.

If you are a Swede you should be ashamed of yourself. I'm an immigrant who thinks Sweden is pathetic and full of cowards. If you still want person robberies on a daily basis, a reality in many Swedish cities, vote for the 7 established parties. But don't complain when you or your children become victims. You chose it.
