In italian oc the pizzo aka extortion on every activity was the first thing that a oc group impose for show that control a territory. While the in sicily and campania the kidnappings was forbitten because attire too much heat so the ndrangheta in 19 70s was leader in the kidnappings (the getty kidnap was an example) and rumors say that in the small village in Calabria there many neighborhoods built ed with the ransom money. The ndrangheta used the ransom money to start the drug trade and when in the 1990 a law was made that blocked the assets of a person in case of kidnapping for dont pay the ransom,the ndrangheta was just deep in drug trade and can easly stop the kidnappings.
There are horrible stories on people that was kidnapped and almost died because treated like animal,chained and left in the cold in caves for months without being able to wash or change the clothes.
