In Chapter 7 We Discuss the Work of Sam Antar

In Chapter 7 we discuss the work of Sam Antar, a convicted felon and former CFO of Crazy Eddie, in helping to analyze and ferret out the fraud at Green Mountain Roasters in September 2012. Today Antar works very closely with the FBI, IRS, SEC, Justice Department, and other federal and state law enforcement agencies in training them to identify and catch white-collar criminals.
In October 2015, Andy Fastow, also a CFO (at Enron) and convicted felon, spoke at the University of Missouri on "Pride and Repentance: The Enron Story," focusing on his personal shortcomings and similar number-fudging he says is still occurring in companies across the world. Despite the damage he caused, Fastow said he didn't break any rules while at Enron but instead found ways around the rules for his own and the company's benefit.
Do you believe that convicted felons should be allowed to benefit from their work and speeches in a financial or reputational way? Use ethical reasoning to support your answer.
