Yet we don't see these scenes in other countries with huge football followings. Germany? Nope. Spain? Nope.
We don't see it with other sports in this country.
Well I'm actually fairly uniquely placed to answer your point as I work in Berlin and have watched a fair chuck of this world Cup in Germany including 2 Germany games and 2 England games and all I'll say is that if you think Germany is clean in this respect you couldn't be further from the truth.
While watching the last Germany game at the Brandenburg gate, the German police embedded plain clothed (and Armed!) officers within the crowds and they were not exactly wasting their time with several morons getting arrested, the difference between there and here is that most of the trouble was dealt with as or before it escalated.
