I can think of few things that have been more toxic to our democracy than the realization that no laws apply to Wall Street, and they will never, ever, ever have to face actual consequences for their crimes. Matt Taibbi on how the SEC covered up potential criminal acts on Wall St.:

Imagine a world in which a man who is repeatedly investigated for a string of serious crimes, but never prosecuted, has his slate wiped clean every time the cops fail to make a case. No more Lifetime channel specials where the murderer is unveiled after police stumble upon past intrigues in some old file – "Hey, chief, didja know this guy had two wives die falling down the stairs?" No more burglary sprees cracked when some sharp cop sees the same name pop up in one too many witness statements. This is a different world, one far friendlier to lawbreakers, where even the suspicion of wrongdoing gets wiped from the record.

That, it now appears, is exactly how the Securities and Exchange Commission has been treating the Wall Street criminals who cratered the global economy a few years back. For the past two decades, according to a whistle-blower at the SEC who recently came forward to Congress, the agency has been systematically destroying records of its preliminary investigations once they are closed. By whitewashing the files of some of the nation's worst financial criminals, the SEC has kept an entire generation of federal investigators in the dark about past inquiries into insider trading, fraud and market manipulation against companies like Goldman Sachs, Deutsche Bank and AIG. With a few strokes of the keyboard, the evidence gathered during thousands of investigations – "18,000 ... including Madoff," as one high-ranking SEC official put it during a panicked meeting about the destruction – have apparently disappeared forever into the wormhole of history.

Under a deal the SEC worked out with the National Archives and Records Administration, all of the agency's records – "including case files relating to preliminary investigations" – are supposed to be maintained for at least 25 years. But the SEC, using history-altering practices that for once actually deserve the overused and usually hysterical term "Orwellian," devised an elaborate and possibly illegal system under which staffers were directed to dispose of the documents from any preliminary inquiry that did not receive approval from senior staff to become a full-blown, formal investigation. Amazingly, the wholesale destruction of the cases – known as MUIs, or "Matters Under Inquiry" – was not something done on the sly, in secret. The enforcement division of the SEC even spelled out the procedure in writing, on the commission's internal website. "After you have closed a MUI that has not become an investigation," the site advised staffers, "you should dispose of any documents obtained in connection with the MUI."

Many of the destroyed files involved companies and individuals who would later play prominent roles in the economic meltdown of 2008. Two MUIs involving con artist Bernie Madoff vanished. So did a 2002 inquiry into financial fraud at Lehman Brothers, as well as a 2005 case of insider trading at the same soon-to-be-bankrupt bank. A 2009 preliminary investigation of insider trading by Goldman Sachs was deleted, along with records for at least three cases involving the infamous hedge fund SAC Capital.
