This study is about howStockholm’s policy for zero tolerance of graffiti from 2007 affected the graffiti culture inStockholm. We have researched what consequences there were for the practice of graffiti, and what consequences there were for the stylistic performance of graffiti. In doing so, we have had two focus group interviews and one deep interview including eight graffiti writers from Stockholm. The individuals in the groups have been practising graffiti for a varied amount of time, but we have representation from both before, and after/during the policy of zero tolerance from 2007.  Our study shows that the result ofStockholm’s policy for zero tolerance of graffiti for the graffiti culture inStockholmwas a ”subcultureification”, a ”stylistic generalization” and the ”subculture’s ambivalent identity”. With ”subcultureification” we mean that the labelling process from the politicians in acting against the graffiti culture and present it as a problem and a deviant and criminal subculture was reinforced within the graffiti culture and resulted in the increased importance of criminalization for the development of sub cultural capital. The ”stylistic generalization” was a consequence of the changed conditions for writing graffiti. Less time and more security have led to a simpler and fast performance and less of the colourful and detailed murals. A consequence which helps keeping the public convinced of the necessity of the zero tolerance policy and the connection between graffiti and criminal damage rather than an artistic expression. The ”subcultures ambivalent identity” referred to the interpretation that the new conditions for writing graffiti changed the way the writers identified the culture. In our research we found three major conflicts regarding if or if not graffiti was ”art”, about practicing legal graffiti or illegal, and how to value graffiti on the internet.   Keywords: Graffiti, subculture, social control, cultural conflict, stylistic progress Sökord: Graffiti, subkultur, social kontroll, kulturell konflikt, stilistisk utveckling   Antal ord: 18 561
