This is an essay in Swedish on the subject of democracy and demonstrations of collective violence. The study is based on a conflict between the youth-house movement in Copenhagen and the state of Denmark - the city of Copenhagen. The focus is over the period December 2006 until January 2008 with reflection on the political movement around the youth-house from the 80's and onwards. This political movement roots back to the late 60's and especially the squatting movement, the BZ, of Europe which had a strong period in Denmark both in the 60's and the 80's. There is also a strong connection to other political movements of anti-fascism, anti-globalisation, queer activism and equal rights.
