When you have hooligans, it's on your police force and FA to address it and collaborate with locals wherever you go. Not just throw your hands up and call them not real fans after they've done shat the bed.
Those fans who create problems know that Croatia is corrupted and you can't get rid of Mamic who is connected with top politicians.
So, they are creating problems on international matches, for example Dinamo in Champions league of Croatia on Euros or World cup.
Where Croatian justice can't deal with Mamic, but Uefa and Fifa.
I have a few "friends" among those troublemakers, or at least among guys who are close to them.
Those guys are slightly too passionate about Dinamo and about following football, and they act as if someone killed their family or something.
Or as if: if you touch Dinamo, I will kill you...
I wouldn't be surprised if they eventually kill Mamic or do something similar.
What is worse, in their heads, those fans believe that everything is justified and they believe that they are fighting for a right cause and that they are victims and good guys here.
More or less, just imagine any war, where both sides think that they are right.
Or imagine terrorism and similar. They all believe that they are right and that they are fighting for a right cause.
So, it is extremely hard to talk or enter into any logical debate with those fans.
You can only get beaten up or killed.
Also, for some of them, if they end in jail or something, they don't care.
They are fighting for a right cause (they think so), and if you put in jail 100 of them, then new 100 of their friends will step in.
