Robert Mazur served for 27 years as a special agent for the IRS Criminal Investigation Division, the Customs Service and the Drug Enforcement Agency working predominantly as a undercover agent working as a money launderer.  Robert wrote two terrific books, "The Infiltrator" and "The Betrayal", the first of which was turned into a movie which starred Brian Cranston as none other than Robert Mazur! Robert joins CSI Chat and we touch on a number of topics including: - How did someone go from working at the Internal Revenue Agency (IRS) to working undercover going up against the most dangerous drug cartels in the world? - What is the mental skill set one needs in order to prepare themselves to go undercover?  How do you prepare your family for this dangerous experience? - What is the "day in the life" of an undercover agent?  How do you deal with the stress and the fear of potentially being caught? Robert is an American hero and an incredible person who has been fighting against the illegal drug trade in the United States his entire life.  We are very lucky to have him join "CSI Chat".
