Obstruction of justice

So sayeth Tom Kean and Lee Hamilton, co-chairs of the 9/11 Commission in today's NY Times:

MORE than five years ago, Congress and President Bush created the 9/11 commission. The goal was to provide the American people with the fullest possible account of the “facts and circumstances relating to the terrorist attacks of Sept. 11, 2001” — and to offer recommendations to prevent future attacks. Soon after its creation, the president’s chief of staff directed all executive branch agencies to cooperate with the commission.

The commission’s mandate was sweeping and it explicitly included the intelligence agencies. But the recent revelations that the C.I.A. destroyed videotaped interrogations of Qaeda operatives leads us to conclude that the agency failed to respond to our lawful requests for information about the 9/11 plot. Those who knew about those videotapes — and did not tell us about them — obstructed our investigation.

Of course, no Bushie cares if someone has obstructed justice. Look at Scooter Libby.
