Mafia US Treasury Department Bureau of Narcotics.

Got the first published hardcover edition about 3 years ago as a gift. A state by state who's who of wiseguys. The last entry appears to be around 1963. Fast forward to a week ago I see an updated soft cover version which is annotated and some of the individuals who were in the first edition left out of the newer edition. Does anyone know why this was? I've got my theory,
What does everyone think?

This is my first post here. I used to post on Porrello's old board years ago.
