Isn't it time to ban hooligans & their clubs?

What happened today in Italy is just wack!!! Hooligans are part of the sport and they should be kept that way. The Atalanta fans just wanted to be heard thats all and who better to do it than with the European Champions visiting. Hooligans aren't just the criminal part of the sport but the social. Many groups represent a group of diverse people or a political party. They use the sport to express themselves! Although i agree in a sense with hooliganism up until the extent where the hooligans control the team. I think that should never happen! Argentina is practically ran by hooligans and it is something tha has affected the sport for a long time. As for the events today it was all the police's fault. He "accidentally" shot a Lazio fan when there was a riot between Lazio and Juve fans.
