I am not getting drawn into that idea but I remember very clearly watching Man Utd fans getting escorted from Goodison back into the city by significant police presence. I literally watched it pass by from the student I was living in at the time and this was less than two years ago.
People get stabbed/killed every week in Europe? Which parts do you mean? I know the thugs in Poland and the like are really bad but if we're talking about the Italian, Spanish, French and German leagues then I think it would be in the news every week.
Also, just because it was going to happen, as you say, does that mean it is acceptable? I mean, we're getting into a wider social issue here so I'll try not to ramble but that kind of sentiment - as maintained by lots of hooligans and associated people in this country - is exactly what is wrong with this country. This is not passion. This is not something that can be unavoidable. This is something that should be concentrated on, since we have 99% of the game sorted out, as you say.
