Yeah I heard about La Gran Familia. I thought it was a set under the Latin Kings. They are indeed very structured.
But I think people's fascination with the mob comes from all those Hollywood-movies. They think the mob is that superior, highly structured, glamorous crime syndicate. A lot of people need to wake up and smell the 21st century, because nowadays the mob is as gritty as any other mafia/street/prison/biker/cartel gang.
NO, and I repeat, NO criminal syndicate is as spectacular in real life as they are in the movies or as the media may want you to believe.
