President Bush has turned the executive branch into a two-way mirror. They get to see everything Americans do: our telephone calls, e-mail, and all manner of personal information. And we get to see nothing about what they do.

Everyone knows this administration has disdained openness and accountability since its first days. That is about the only thing it does not hide. But recent weeks have produced disturbing disclosures about just how far Mr. Bush’s team is willing to go to keep lawmakers and the public in the dark.

That applies to big issues — like the C.I.A.’s secret prisons — and to things that would seem too small-bore to order up a cover-up.

Vice President Dick Cheney sets the gold standard, placing himself not just above Congress and the courts but above Mr. Bush himself. For the last four years, he has been defying a presidential order requiring executive branch agencies to account for the classified information they handle. When the agency that enforces this rule tried to do its job, Mr. Cheney proposed abolishing the agency.
