Most likely. I remember reading about how Rahm Emmanuel got his start as a bag boy for the Chicago mob. The thing about the Chicago mob, though, is they still take "omerta" very seriously. It's tough to nail them (although the Justice Department did manage to clean out a whole bunch of judges some years ago).
Not to worry - - Patrick Fitzgerald is on the job.
Ah, yes, Paddy Fitzgerald. He’s still working on the case against Capone and Big Bill Thompson, right ?
