The Decavalcante family is much more viable than detroit, the reason there hasn't been many indictments against the Decavs is after 2003 when they had much of the family indicted the FBI felt a job well done and after get a blow on a smaller family like that they don't go straight back to hammering them, just like philly after merlino,Stanfa and many others were jailed they really didn't do anything until recently, also when talking about Chicago i mostly meant hard drugs not pot,

Francesco Guarraci was indicted in 2009 of extorting business
James Castaldo, a soldier was convicted of hiring a hitman
Also some other cases, and the Decavalcante crime family was mentioned in the big roundup in January 2011 so i believe them to still be viable
