This is The Gangland Wire podcast. The host, Gary Jenkins is a retired KC cop who was an OC investigator in KC. His podcast is usually pretty good but he brings on author Bill Friedman to talk Capone's early days. Tons of great info. I didn't realize the St Val massacre was really Jack McGern's operation. He ties in Capone to the national scene as far as bootlegging (Lucianno, Costello, Dalitz, etc...). I thought it was a great listen.
