also, it is silly to believe the criminal organizations operate in Italy alone.

For example. 'ndrangheta has been operating in Germany for years (see the Duisburg massacre), and a lot of camorra's drug trafficking goes through Spain.

There have been some very high level cases even recently, such as the killing of Ján Kuciak in Slovakia who was likely murdered because he was investigating the connection between ndrangheta and the Slovakian government.
