Sorry, but a European scale is a stupid concept.
OC group can't be ranking or scaling.
For exmaple Malta play a important role for oil smuggling. Nobody can't hidden a massiv Oil distribution network.
The maltese wealth families give some guy in this biz protection. In Greece you have the same thing.
It is unimportant how powerful you are anywhere in the world. You have to be powerful in Malta. And in Malta it's mostly Maltese
When Russians get new passports in Malta for 10,000, that's convenient for them. But the Maltese make it possible.
Division of labor also exists with criminals.

They killed a young journalist. Not the Cosa nostra, no they link was directly to the goverment to the rich families.
Same for other country's. Cosa nostra are powerful. But its complete different between his home and cells in other countries.

Scaling make no sense. In Cosa Nostra different families have very different influences. They don't always share it.

But this is offtopic.

I think Sardinia bandits never get this kind of protection. Never forgett after the II WW cosa nostra was finish. But they get "green light" to rebuild because they need them to fight against left groups.
Sardinia never had a secret society like CN. But of course they have criminals groups. In old days they also had vendettas.
