This book was written as a tribute to all the agents who were assigned to Criminal Squad #1, more commonly referred to as the C-1 Squad, of the Chicago Division of the FBI from 1957 to 1976, a period of nineteen years. These agents were pioneers, who were required to wage war against one of the most powerfully entrenched organized crime organizations in the country since the days of Al Capone. It was at a time when the FBI did not have all the tools or legislation necessary to combat organized crime but they accomplished their goals aggressively with whatever means were available. This is a story of the unique challenges confronting these dedicated agents and the incomparable results achieved which resulted in severely disrupting and curtailing the activities of the Chicago mob. Mr. Inserra also chronicles parts of his career prior to and following his FBI experiences.
