Apparently in Germany the problem has been solved by making the teams responsible and fineable. I do not understand why this can't be done here!

Mind you apparently you are having problems with Hells Angels, the mob and sex trafficking.

Maybe this international shaming will get Italy to actually do something to alter this nightmare. The guy is not being punished, indeed he is giving interviews the day after. Local hero etc.

How are they allowed to enter with smoke bombs, fireworks etc?

I truly loathe what competitive sports allied with business is doing to countries all over the world. Cf Brazil... Olympics, Beijing, Sochi yada yada. The worst of human nature brought out... Trust Italy to make it even more grotesque than other countries.
