I would once again recommend viewing this one hour program which I assume will be available on the PBS Web site. I would not recommend it to anyone with a weak stomach or high blood pressure. It features such common folk as a documentary film maker who decided to look for whistleblowers and managed to find dozens of them by doing it in his "spare time." He wonders how that could happen when investigators have been at it for years with little success. A few of those whistleblowers are interviewed and their stories are truly mind boggling. One who worked for one of the major banks sent emails right up the chain of command to the CEO calling attention to boxes full of mortgage agreements that were defective in the range of 60%. That range grew to 80% over time. Management's instructions were to ignore the defects and to package the flawed mortgages for sale. The PBS interviewer expresses amazement that this could have happened but is told that the senior bankers could only be pursued through civil, not criminal, avenues because the prosecutors could not be confident that they could prove "intent." The viewer is left with a definite impression that the bankers are in control of both the legal and political systems. Not a pretty picture.
