Destruction of C.I.A. Tapes Cleared by Lawyers

Correction Appended

WASHINGTON, Dec. 10 — Lawyers within the clandestine branch of the Central Intelligence Agency gave written approval in advance to the destruction in 2005 of hundreds of hours of videotapes documenting interrogations of two lieutenants from Al Qaeda, according to a former senior intelligence official with direct knowledge of the episode.

The involvement of agency lawyers in the decision making would widen the scope of the inquiries into the matter that have now begun in Congress and within the Justice Department. Any written documents are certain to be a focus of government investigators as they try to reconstruct the events leading up to the tapes’ destruction.
