I saw Carmine "Snake" Persico which is a good story.

I don't get it why you said it's waste when they put Kukinski on Mobsters? Well, he's actually work for Demeo and became a hit man for him and he killed him.

I remember they even put Frank Lucas and Nicky Barnes on Mobsters show.

I'm assuming you think Mobsters = Mafia, that's not the case.
