I think I've seen that American Justice one - it's about wire tapping and has a lot on the pizza connection. from what I remember it was really awesome, I haven't seen any other mob doc/show like it . It used to be on Netflix streaming but I don't think it is anymore. I remember one of the agents on there saying they had problems interpreting what they were saying for a while; a lot of them were speaking a really obscure, almost dead dialect of the sicilian language
