We recently presented a look at some of the most notorious financial felons of contemporary times.

Since then, news has included the indictment of Mark Cuban for insider trading in a case that is somewhat reminiscent of Martha Stewart's case. According to the SEC, the billionaire entrepreneur asked his broker to sell all his shares of Mamma.com after the company's CEO confidentially told him of an impending stock offering that would dilute the value of all existing shares. By selling before the information became public, Cuban is said to have sidestepped losses of more than $750,000. Cuban insists, though, that no agreement existed to keep the information confidential.

And then there was the indictment in Texas of Vice President Dick Cheney, along with former U.S. Attorney General Alberto Gonzales and others. There seems to be a conflict of interest between the vice president's influence on the federal agency that oversees federal immigration detention centers and his substantial holdings in Vanguard Group, which invests in private prison companies. But does the lame-duck county district attorney, who was a no-show in court, have the authority to bring charges against federal officials with regard to federally run institutions?

Question for Henry Blodget's many detractors: Are you mad that Michael Milken has become respectable?

Blodget and Milken symbolized the excesses of their internet bubble and 1980s respectively. Both were punished for their misdeeds. Milken, who went to prison, now devotes his time to his philanthropic work and an economic think tank. Blodget received a lifetime ban from the securities industry, a punishment he deserved.

Now pundits including MarketWatch's David Weidner and my colleague Zac Bissonnette say they are outraged that Blodget's writing is published in leading news outlets including the New York Times. What about Milken? Bloomberg News just interviewed him about the housing crisis. Should my former employer have killed the story given Milken's notorious past? Of course not.

Milken did his time and paid his fines. He's a brilliant man who still has plenty of interesting things to say. Same goes for Blodget. To be clear, investors shouldn't forgive or forget them for what they did. As far as I know Blodget has stayed out of legal trouble since he was banned from the securities industry. In 1998, Milken agreed to pay a $47 million fine to settle an SEC complaint that he violated his lifetime ban.
