The more recent years. Like 2000 to the present. The mob, from the 1930's through the 1990's has been covered sufficiently from any number of sources. Going back to the early part of the 20th century, and late 1800's, sort seems sort of futile beyond a certain point. From 2000 to the present is now, is happening, and is continually moving. Personally, I think it's fascinating to watch the families that still tread water, while observing the decay overall.
