While Cioffi and Tannin are probably as greedy as the commenters claim, personally they were reasonably decent for bankers. Their role in the financial meltdown was small. Some of the major culprits are now serving in the Obama Administration:
While Jewish Wallstreeters like Madoff can often count on kid-glove treatment from regulators and the US attorney thanks to the power of corrupt Jewish social networks, Cioffi being of Italian ancestry might not have been quite as plugged-in as some of his Jewish colleagues. Tannin is half-Jewish as I remember and may have been considered expendable.
The Dealbook email also included a followup on Intel-Galleon Group insider trading scandal: Rajaratnam Moves to Unseal 2000 Case Against Informant. Rajaratnam was vulnerable because the Indian social networks do not seem to have quite as much penetration into the US attorney and regulator offices as the Jewish Zionist networks of trust do.
