"If they keep beating you, pay 'em." That's how corporate law firms treat federal prosecutors, according to Harvey Silvergate at Forbes.
Silvergate has a good piece, "The Revolving Door at The Department of Justice," which leads with Michael Loucks, who was good enough at prosecuting drug companies that the drug companies hired him. Silvergate has a catalogue of revolvers, and he makes this observation:
Underlying the revolving door is a pernicious underbelly of overzealous and often unfair prosecutions, juked conviction stats, and a culture of plea-bargaining that is spiraling out of control, all in order to bring down some of the biggies in the business world. In short, the revolving door is facilitated by a federal criminal justice system geared more for making prosecutors’ reputations on the scalps of private sector companies and executives, than for achieving true justice.
This is parallel to what I say about the regulatory and legislative revolving doors: the more aggressive the lawmakers and regulators are, the more valuable they make themselves to the private sector. In other words, big government is the grease that makes the door revolve faster.
