Robert Siegel talks to Michael Greenburg about his book, "The Mad Bomber of New York." It's the story of George Metesky who anonymously left many bombs around the city in the post-war era. Between 1940 and 1957, he placed 33 bombs in busy areas of the city — phone booths, restrooms, movie theaters. The NYPD called the search for the perp "the greatest manhunt in the history of the police department." In the aftermath of the killing of Osama bin Laden, we recall this earlier episode of a man who brought chaos and anger to the Big Apple.
