I think they have used wikipedia as a reference here for difronzo and also it is questionable that the adams family is still active or even that powerful still. And can you really rank bellomo with the most powerful crime bosses in the world? maybe america.

They also missed out dawood ibrahim who runs d company, he's a pretty obvious choice for the list. http://www.dailymail.co.uk/indiahome/ind...o=feeds-newsxml
