Answering such a question — the equivalent of determining why a dog did not bark — is anything but simple. But a private meeting in mid-October 2008 between Timothy F. Geithner, then-president of the Federal Reserve Bank of New York, and Andrew M. Cuomo, New York’s attorney general at the time, illustrates the complexities of pursuing legal cases in a time of panic. At the Fed, which oversees the nation’s largest banks, Mr. Geithner worked with the Treasury Department on a large bailout fund for the banks and led efforts to shore up the American International Group, the giant insurer. His focus: stabilizing world financial markets.
