Jeff Connaughton writes: Long silent and now contradictory, President Obama needs to deliver a clarifying speech about our financial markets and the rule of law. Speaking in Kansas on December 6, he said, “Too often, we’ve seen Wall Street firms violating major anti-fraud laws because the penalties are too weak and there’s no price for being a repeat offender.” Just five days later on 60 Minutes, he said, “Some of the least ethical behavior on Wall Street wasn’t illegal.” Which is it? Have there been no prosecutions because Wall Street acted legally (albeit unethically)? Or did Wall Street repeatedly violate major anti-fraud laws (and should thus find itself in the dock)?

The President is confusing “legal” with “difficult to prosecute successfully.” The Justice Department’s repeated decisions not to risk losing at trial against Wall Street executives don’t make these person’s actions legal. (If a district attorney can’t prove the actual thief stole your wallet, that doesn’t make stealing legal. It simply means that, regrettably, a malefactor goes unpunished.) As Securities and Exchange Commission Enforcement Director Robert Khuzami said in Senate testimony in 2009, Wall Street perpetrators “are smart people who understand that they are crossing the line” and “are plotting their defense at the same time they’re committing their crime.”

Moreover, the President is misleading us when he says that Wall Street firms violate anti-fraud law because the penalties are too weak. Repeat financial fraudsters don’t pay relatively paltry — and therefore painless — penalties because of statutory caps on such penalties. Rather, regulatory officials, appointed by Obama, negotiated these comparatively trifling fines. This week, the F.D.I.C. settled a suit against Washington Mutual officials for just $64 million, an amount that will be covered mostly by insurance policies WaMu took out on behalf of executives, who themselves will pay just $400,000. And recently a federal judge rejected the S.E.C.’s latest settlement with Citigroup, an action even the Wall Street Journal called “a rebuke of the cozy relationship between regulators and the regulated that too often leaves justice as an orphan.”

The Obama Justice Department hasn’t tried a single Wall Street executive in a criminal court. Against a handful, it decided to let the S.E.C. bring civil charges of fraud, which are easier to prove. So if defendants’ wrists are merely being slapped by the S.E.C. instead of cuffed by the Justice Department, Obama has only his appointees to blame.

For three important reasons, the President needs to explain why the Justice Department has filed away its investigations of big banks and Wall Street firms without indicting anyone. First, American confidence in the system is deeply shaken. Second, it strains credulity for millions of Americans — and has impelled thousands of them to occupy public places in protest — that no banking or insurance executive deserves criminal prosecution for the actions that brought on the financial crisis. Third, by failing to prosecute a single high-profile Wall Street actor today, the Administration is failing to deter financial fraud tomorrow.
