Who sits on the SAG that made the decision?
Clearly if they didn’t have a reputation for violence then they wouldn’t have been banned, but I think it’s bullshit to just straight up ban any team’s fans from a game, and if you haven’t exhausted all options in terms of policing then you’ll inevitably open yourself up to accusations that something more sinister is behind it.
Football fans shouldn’t be treated as criminals by default, surely people on this forum have experienced enough bullshit during their own travels to know this.
