Municipal bonds are where a lot of the political kickbacks and corrupt deals are typically hidden, so I can't say I'm surprised. In fact, it's sort of funny that the governments dealing with these guys apparently thought they could trust them, considering how crooked the business is. Lie down with dogs, rise up with fleas, as the nuns used to say:

March 26 (Bloomberg) -- JPMorgan Chase & Co., Lehman Brothers Holdings Inc. and UBS AG were among more than a dozen Wall Street firms involved in a conspiracy to pay below-market interest rates to U.S. state and local governments on investments, according to documents filed in a U.S. Justice Department criminal antitrust case.

A government list of previously unidentified “co-conspirators” contains more than two dozen bankers at firms also including Bank of America Corp., Bear Stearns Cos., Societe Generale, two of General Electric Co.’s financial businesses and Salomon Smith Barney, the former unit of Citigroup Inc., according to documents filed in U.S. District Court in Manhattan on March 24.

Gee, look how many were firms that were already taking money from us on the front end. They wanted the back end, too?

The papers were filed by attorneys for a former employee of CDR Financial Products Inc., an advisory firm indicted in October. The attorneys, as part of their legal filing, identified the roster as being provided by the government. The document is labeled “list of co-conspirators.”

None of the firms or individuals named on the list has been charged with wrongdoing. The court records mark the first time these companies have been identified as co-conspirators. They provide the broadest look yet at alleged collusion in the $2.8 trillion municipal securities market that the government says delivered profits to Wall Street at taxpayers’ expense.

Excuse me while I rush to my fainting couch. I'm a little dizzy from the shock.

“If the government is saying they are co-conspirators, the government believes they have sufficient evidence that they can show they were part of the conspiracy,” said Richard Donovan, a partner at New York-based law firm Kelley Drye & Warren LLP and co-chair of its antitrust practice. Donovan isn’t involved in the case.

The government’s case centers on investments known as guaranteed investment contracts that cities, states and school districts buy with the money they receive through municipal bond sales. Some $400 billion of municipal bonds are issued each year, and localities use the contracts to earn a return on some of the money until they need it for construction or other projects.

The Internal Revenue Service sometimes collects earnings on those investments and requires that they be awarded by competitive bidding to ensure that governments receive a fair return. The government charges that CDR ran sham auctions that allowed the banks to pay below-market interest rates to local governments.

[...] Banks may choose to cooperate with prosecutors because in light of the government bailout funds they’ve received “a guilty plea would just be an absolute disaster for some of these companies,” said Nathan Muyskens, a partner at Shook, Hardy & Bacon in Washington and former trial attorney with the Federal Trade Commission’s Bureau of Competition.

“There have been antitrust investigations where there have been companies involved that were just never indicted,” he said in a phone interview.

Yes, this is what's now known as "too big to jail." Why, they're too big for just about anything!

At the same time, the government will probably focus on seeking to convict individual bankers, he said.

“When someone goes to jail for five years, that resonates,” he said. “When a company pays $200 million, it’s simply a balance sheet issue. Jail time is what captures corporate America’s attention.”
