Violence associated with football matches has a long history, dating back to medieval England. Initially, supporters were seen as dangerous, requiring riot police and enclosures. However, since the turn of the millennium, a new method within the Swedish Police, translated to Special Police Tactics (SPT), has been introduced and which is based on the new theories of mass psychology which views the crowd as consisting of individuals with different social identities who can be influenced by circumstances and police actions. The police should facilitate and support the positive majority while selectively intervening against the violent minority through prosecution and stadium bans. The conflict-reducing principles, particularly differentiation, are central to distinguishing between disorderly individuals and legitimate participants, aiming to maintain order and safety at events. This approach reduces disturbances and makes football matches safer for all supporters.This thesis aims to examine police officers' experiences with the prosecution and exclusion of disorderly individuals at football-matches and analyse what impact these measures have on the public order situation at these events. The focus is on stadium bans and improvements in working methods. The research questions address police perceptions of prosecution and exclusion, their impact on public order, and potential improvements.Stadium bans are considered an effective tool for excluding problematic supporters but measuring the impact of prosecution and exclusion is challenging. Stadium bans are seen by the supporters as a harsher punishment than legal consequences and they also have a more long-term result.Improvements to make the exclusion of disorderly individuals even more effective include specific training for investigators, focusing on long-term results, joint exercises and closer collaboration between operational and investigative units.
