"Guardia di Finanza is dealing with anything that has to do with big money, finances (finanza)

Direzione Nazionale Antimafia is where any undercover agents would come from. They are anti-mafia on a national level.

A lot of mafia blitzes are performed by Squadra Mobile, with special units being brought in for high profile arrests, usually for fugitives, breaking into their hideouts, etc."

I know that in the NYPD they have special units for organized crime in the city and the state of NY does too. Do you know if any Italian cities or states have their own mafia investigation agencies or are they generally viewed as being in the pocket of local organized crime?
