From CBS News:

Two whistleblowers offer a rare window into the root causes of the subprime mortgage meltdown. Eileen Foster, a former senior executive at Countrywide Financial, and Richard Bowen, a former vice president at Citigroup, tell Steve Kroft the companies ignored their repeated warnings about defective, even fraudulent mortgages. The result, experts say, was a cascading wave of mortgage defaults for which virtually no high-ranking Wall Street executives have been prosecuted.
