CBS defense of Rather hints at bigger story: "Of all the loopy statements made by Dan Rather in the 10 days since he decided to throw his career away, my favorite is this, from Dan's interview with the Washington Post on Thursday: ''If the documents are not what we were led to believe, I'd like to break that story.'' Hel-looooo? Earth to the Lost Planet of Ratheria: You can't ''break that story.'' A guy called ''Buckhead'' did that, on the Free Republic Web site a couple of hours after you and your money-no-object resources-a-go-go ''60 Minutes'' crew attempted to pass off four obvious Microsoft Word documents as authentic 1972 typewritten memos about Bush's skipping latrine duty in the Spanish-American War, or whatever it was."
