New York City in the mid to late 19th century was host to some of the most colorful criminals in American history - and equally colorful policemen who battled them. Police Chief Thomas Byrnes was considered one of the best sleuths in the world, yet there were always plenty of sensational cases to solve and elusive crooks to catch. My guest John Oller is author of "Rogues' Gallery: The Birth of Modern Policing & Organized Crime In Gilded Age New York". He shares stories of some of his favorite period characters - including crime boss Marm Mandelbaum, bank robber extraordinaire George Leonidas Leslie, and Danny Driscoll, leader of the notorious Whyos Gang.
