We know what a criminal White House looks like from “The Final Days,†Bob Woodward and Carl Bernstein’s classic account of Richard Nixon’s unraveling. The cauldron of lies, paranoia and illegal surveillance boiled over, until it was finally every man for himself as desperate courtiers scrambled to save their reputations and, in a few patriotic instances, their country. “The Final Days†was published in 1976, two years after Nixon abdicated in disgrace. With the Bush presidency, no journalist is waiting for the corpse to be carted away. The latest and perhaps most chilling example arrived in July 2008 from Jane Mayer of The New Yorker, long a relentless journalist on the war-on-terror torture beat. Her book “The Dark Side†connects the dots of her own past reporting, and that of her top-tier colleagues, to portray a White House that, like its prototype, savaged its enemies within almost as ferociously as it did the Constitution... In her telling, a major incentive for Mr. Cheney’s descent into the dark side was to cover up for the Bush White House’s failure to heed the al-Qaeda threat in 2001. Jack Cloonan, a special agent for the F.B.I.’s Osama bin Laden unit until 2002, told Ms. Mayer that Sept. 11 was “all preventable.†By March 2000, according to the C.I.A.’s inspector general, “50 or 60 individuals†in the agency knew that two al-Qaeda suspects — soon to be hijackers — were in America. But there was no urgency at the top. Thomas Pickard, the acting F.B.I. director in the summer of 2001, told Ms. Mayer that when he expressed his fears about the Qaeda threat to Mr. Ashcroft, the attorney general snapped, “I don’t want to hear about that anymore!â€
