Just a short list is staggering. Who put that bogus “uranium from Africa” into the crucial prewar State of the Union address after the C.I.A. removed it from previous Bush speeches? How high up were the authorities who ordered and condoned torture and then let the “rotten apples” at the bottom of the military heap take the fall? Who orchestrated the Pentagon’s elaborate P.R. efforts to cover up Pat Tillman’s death by “friendly fire” in Afghanistan?

And, for extra credit, whatever did happen to Bush’s records from the Texas Air National Guard?

The biggest question hovering over all this history, however, concerns the future more than the past. If we get bogged down in adjudicating every Bush White House wrong, how will we have the energy, time or focus to deal with the all-hands-on-deck crises that this administration’s malfeasance and ineptitude have bequeathed us? The president-elect himself struck this note last spring. “If crimes have been committed, they should be investigated,” Barack Obama said. “I would not want my first term consumed by what was perceived on the part of Republicans as a partisan witch hunt, because I think we’ve got too many problems we’ve got to solve.”

Henry Waxman, the California congressman who has been our most tireless inquisitor into Bush scandals, essentially agreed when I spoke to him last week. Though he remains outraged about both the chicanery used to sell the Iraq war and the administration’s overall abuse of power, he adds: “I don’t see Congress pursuing it. We’ve got to move on to other issues.” He would rather see any prosecutions augmented by an independent investigation that fills in the historical record. “We need to depoliticize it,” he says. “If a Democratic Congress or administration pursues it, it will be seen as partisan.”

We could certainly do worse than another 9/11 Commission. Among those Americans still enraged about the Bush years, there are also calls for truth and reconciliation commissions, war crimes trials and, in a petition movement on Obama’s transition Web site, a special prosecutor in the Patrick Fitzgerald mode. One of the sharpest appointments yet made by the incoming president may support decisive action: Dawn Johnsen, a law professor and former Clinton administration official who last week was chosen to run the Office of Legal Counsel in the Department of Justice.

This is the same office where the Bush apparatchik John Yoo produced his infamous memos justifying torture. Johnsen is a fierce critic of such constitutional abuses. In articles for Slate last year, she wondered “where is the outrage, the public outcry” over a government that has acted lawlessly and that “does not respect the legal and moral bounds of human decency.” She asked, “How do we save our country’s honor, and our own?”

The last is not a rhetorical question. While our new president indeed must move on and address the urgent crises that cannot wait, Bush administration malfeasance can’t be merely forgotten or finessed. A new Justice Department must enforce the law; Congress must press outstanding subpoenas to smoke out potential criminal activity; every legal effort must be made to stop what seems like a wholesale effort by the outgoing White House to withhold, hide and possibly destroy huge chunks of its electronic and paper trail. As Johnsen wrote last March, we must also “resist Bush administration efforts to hide evidence of its wrongdoing through demands for retroactive immunity, assertions of state privilege, and implausible claims that openness will empower terrorists.”
