the media does exaggerate abit even at the mobs peak of power. Many experts have come forward and said that valachi may not have been that accurate in his description of the structure of lcn.
The hierarchy of i.e bosses, underboss, consig,capos and perhaps a few of the highranking soldiers in each crew are probably the organised ends of it but everyone underneath is just a mish mash of shifting alliances and criminals under their protection from where most of the money comes from. Newer crime groups dont follow rigid structures like this, which makes the leaders harder to identify. The lcn structure is one of the reasons as to why the feds are able to take them down so often on rico charges.
