The Italian police unfortunately stopped Italian football club Lazio from gaining the owners they deserve. Current Lazio club president Giorgio Chinaglia has been the run from Italian cops in the U.S. since 2006 for some financial shenanigans. Now the Casalesi clan in the Camorra (an organized crime group, basically Naples' version of Sicily's Cosa Nostra) tried to buy Lazio with laundered money.
Lazio fans are typically fascist. This actually is not an exaggeration: Der Spiegel has a picture of Lazio fans standing en masse holding a sign that reads "Auchwitz is your home, the ovens your houses"; they also had a sign rhyming the club Livorno's name with "forno", the Italian name for oven (Livorno is a Leftist/Communist club and the city had a lot of Jews before WW2), their most popular player was known for giving the Hitler salute to the fans; they wave pictures of Bennito Mussolini in the stands; Lazio fans honored Arkan, the Serb guilty of war crimes in Bosnia (and a friend to Sinisa Mihailovic, a Serb who plays for Lazio); I could go on but you get the idea.
It would be true irony if this club was stuck with the Camorra as owners. Unfortunately I am not an expert in Italian organized crime but Wikipedia says that the Camorra owns the rights for trash disposal in Naples - you might have heard about the trash piling up in Naples recently.
Money in the soccer world is extremely liquid (like in the recent Carlos Tevez deal) and the sums are very large (bigger than the local pizza parlor), which I guess makes it attractive to rich criminals. My guess is that given the exceptional liquidity of money in football (another word might be corruption), owning a football club would be a great part of a money laundering chain for a large organized criminal organization with a lot of cash to clean.
I leave you with a picture of true Lazio fans:
Too bad these guys didn't get screwed.
