Bernie Ebbers can't be resting easy after Thursday's latest installment of Executives in Chains, brought to you by the Justice Department. Still, some old hands on the white-collar fraud bar caution that the WorldCom perp walk is hardly certain to lead to a cake walk. It's clear that investors and politicians alike are crying for action in the collapse of the Clinton, Miss., telecom behemoth. Billions of dollars were lost by shareholders and workers while top executives of the company continued to rake in millions in salary, bonuses, executive loans, stock sales and other perks. Even in Wall Street's summer of discontent, the always-deep divide between the insider and the outsider has rarely seemed more bottomless -- or more heartless. But it's that very sentiment, spurring a nearly unanimous cry to action from the political classes, that nettles people like former federal prosecutor Seth Taube. It seems nearly certain that part of the prosecution's plan is to use its strongest cases, such as the one against the financial execs who signed off on the company's expense accounting, to turn WorldCom's ranks against its generals -- in this case, the big fish CEO Ebbers. All the same, Taube and other observers worry that a case brought as swiftly as the one against WorldCom's former financial officers Scott Sullivan and David Myers may in some cases sacrifice thoroughness for speed. "I continue to be concerned that the rush to justice in times of public frenzy is always a risk," says Taube, a former Securities and Exchange Commission prosecutor turned corporate defense attorney. "When the government moves quickly it's tough to meet the burden of proof."
