How can he hire a lawyer to file criminal charges? Thats the state's job. You dont have to hire a lawyer for criminal prosecutions.
Yeah, that part seems odd. An individual can press charges or report crime to the authorities, at which point a prosecutor can determine whether or not to follow through. Defamation is an actual crime in Croatia, the sort of law that can help keep the press in line when the government is as sensitive as Evans. I would be surprised (and quite amused) if the government agreed to spend tax dollars to pursue criminal charges in such a case.
But when you are confident that no one will contest the charges, you can file away and bluster all you want online. The problem will be the aftermath, when the 'defendants' continue to poke fun at him and mock him endlessly even after they were all 'convicted' of the crime of insult.
