" Lamore took his doubts to his boss, Robert Sollazzo, who had doubts too. But not enough doubts. As the SEC postmortem on the Madoff case concluded, “Sollazzo did not find that Madoff’s claim to be trading on ‘gut feel’ was ‘necessarily…ridiculous.’” The SEC defaulted to truth, and the fraud continued. Across Wall Street, in fact, countless people who had had dealings with Madoff thought that something didn’t quite add up about him. Several investment banks steered clear of him. Even the real-estate broker who rented him his office space thought he was a bit off. But no one did anything about it, or jumped to the conclusion that he was history’s greatest con man. In the Madoff case, everyone defaulted to truth—everyone, that is, except one person. "
