The 'ndrangheta have fewer informants than other organizations, because they are more blood family based than camorra and cosa nostra. The only exception is the province of Cosenza where the clans formed as business alliances, not with family ties. I read the only boss in Cosenza really respected by the Reggio Calabria bosses is Francesco Muto from Cetraro. A tough bastard, that one. Tough, because did 10 years of 41-bis prison regime, and bastard because whacked the honest politician Giannino Losardo (honest politicians are too few in this world to treat them like this).
