There's no doubt Mamić used them when he needed their "unbias" assistance, though you're pulling shit out of your arse if you think Mamić got FARE involved in Croatian football.
FARE is a "strategic parter" of UEFA.

So why do you think Mamić got them involved in Croatian football? Didm't UEFA do that? There are two groups in Croatia accredited as FARE spokespeople, Stevanović's Korak Naprijed and the Udruga Roma.
Here's Mamić from that same press conference criticizing Stevanović and his udruga for exactly the same thing that happened against Norway. The UEFA delegate wrote "satisfactory" for the fans behaviour but FARE (Stevanivić, not the Roma society the president of whom is there with him) sent UEFA a different report saying fans were "racist".

Your version the story doesn't hold water HS, Mamić was an outspoken critic of this Stevanović fellow and his udruga, your picture is supposed to prove that Mamić is ultimately to blame for all tis, but you forgot to mention that at that press conference, the exact one your pic is of, he was blasting Stevanović and his udruga for changing the official match report and sending incriminatory info to UEFA, all with Jovanović's blessing.
Jovanović would have given his right nut for a piece of Mamić or the HNS, or to destroy the cult of the NT as is happening right now and has been for a few years. Mamić didn't mince words when he called a hater of everything Croatian, this really must have ruffled feathers to the sensitive souls who are ever so fragile.
Consider this:
Perhaps those thugs who threw flares in Milan are anti-Croatian mercanaries paid off by those more popwerful than Mamić? Perhaps the people in the shadows who pay off the journalists and have theirguy in FARE sensationalise everything are proven anti Croats and powerful politicians like Milanović and his ministers who eat 10 Mamićs for breakfast? Maybe their ploy is to get us thrown out of the euros? To make the fans turn on the team? To destroy the cult of the NT and with it the last vestige of Croatian patriotism? Isn't it also a huge coincedence that both Jovanović and Stevanović just happen to be Croatian Serbs? This makes a lot more sense to me than spinning bullshit and posting out of context pics in a desperate attempt to make the pieces of the puzzle fit.
Conspiracy theories are fun.
