 The lack of dedicated sections for opposing fans creates even further disincentive for them to travel to away games.All of these reduce the chances of hooliganism, eliminate the need to segregate fans from opposing teams, and ultimately negate the threat of closed door game due as a consequence of fan violence.In rare circumstances where a serious incident has occurred (such the 2004 Pacers–Pistons brawl in the NBA), sports authorities have leaned toward identifying and excluding the specific people involved as opposed to indiscriminately punishing the wider, law-abiding fan base.
