The New York Times's explanation of its decision to report, after what it said was a one-year delay, that the National Security Agency is eavesdropping domestically without court-approved warrants was woefully inadequate. And I have had unusual difficulty getting a better explanation for readers, despite the paper's repeated pledges of greater transparency. For the first time since I became public editor, the executive editor and the publisher have declined to respond to my requests for information about news-related decision-making. My queries concerned the timing of the exclusive Dec. 16 article about President Bush's secret decision in the months after 9/11 to authorize the warrantless eavesdropping on Americans in the United States. I e-mailed a list of 28 questions to Bill Keller, the executive editor [of the New York Times], on Dec. 19, three days after the article appeared. He promptly declined to respond to them. I then sent the same questions to Arthur Sulzberger Jr., the publisher, who also declined to respond. They held out no hope for a fuller explanation in the future. The top Times people involved in the final decisions [are] refusing to talk and urging everyone else to remain silent.
