Well what do you want to hear?
Some criminal/alcoholic in his 30:s-40:s died when the police was arresting him. His mother claims the police killed him, a witness or two says that the Police were rough on him. The prosecuters decided that there were no grounds to press charges so the case was dropped.
Some journalist got hold of the case, and for a while everyone was screaming police brutality at the top of their lungs, so another prosecuter took a look at the case and agreed with prosecuter #1 that there were no grounds to press charges so the case was dropped again.
More screams in the media, complete with some sob-story on tv where the mother explains what a good kid her son really was. Another investigation, this time by the highest ranking prosecuter in Sweden. He agreed with prosecuter #1 and #2 and decided that there were no grounds to press charges and the case was dropped again.
So to answer your question: In Sweden people are considered innocent until proven guilty. Strangely enough that applies to cops too. In this case three different prosecuters went over the case and they all agreed that the cops had not done anyting criminal. The media thinks this is wrong though, so once in a while we get a new tv program about the case.
Its the same thing as the cops who shot the anti-EU protester at the EU summit in Gothenburg in the summer of 2001. There were riots when lots of anarchists and whathaveyou tried to storm the meeting. They were throwing rocks at the police, and generally turning Gothenburg into a war zone. A group of 6-7 cops found themselves cornered by a mob, and they were trying to retreat, weapons out. One of the cops was hit in the head by a rock and lost conciousness. When a protester came to throw a rock at the downed cop, another cop shot the protester.
3 prosecuters have decided that it was a clean shooting, no charges has been brought against the cop, the protester went to prison though, something that apparently frustrated the he** out of some people. Some journalist must have made it his personal crusade to get the cop who used his weapon fired or something. Like once every month we get a new tv program about the protester who got shot and how horrible it is that the police can do whatever they want etc etc blah blah (picture rolleyes here)
