I came across a post about a Frenchman who suffered extreme injuries while traveling to Serbia to watch Toulouse take on Partizan Belgrade. Its from a blog that I check out daily called www.theoffside.com. The blog brings up an interesting point that offenses like this cannot go unpunished, but its difficult to punish a club for what happened outside of its jurisdiction (a bar in this case). To resolve this dilemma the writer suggests that football as a whole needs to start being taken less seriously. This was an interesting opinion from a blog which does all it can to promote football from all across the world (visit it and you’ll see what I mean).
In the U.S. there is american football and baseball hooliganism, occasionally. Strictly territorial. Nothing like the political groups involved in European hooliganism. However, I will say that sports fanaticism is a working class phenomenon.
