Would the Mafia protect this family?

So i was watching American Me. If you have watched it. It's about Rudy Cadena the guy that started the Mafia. And how it grew and grew. And i was talking to my teacher and he said he's friends dad used to be friends with the brothers and sisters of Rudy Cadena. And how they are still alive and stuff. And i was wondering. Could the Mafia hurt them or protect them. I mean there family started it all. And would they have alot of money. Thanks you.
