The CIA Torture Tapes

In 2005, the CIA destroyed videotape that showed interrogations of terrorist suspects.  Today's New York Times reports that CIA lawyers gave written permission--despite advice from the White House and the Department of Justice, and without asking their own boss.  CIA Director Michael Hayden says the objective was protecting the identities of the interrogators themselves.  Today, Hayden was called to testify before the Senate Intelligence Committee—behind closed doors, about why the videotapes, despite advice from the White House. Outside the closed hearing, Democrats and Republicans are among those suggesting possible crimes of torture and obstruction of justice. Might the tapes have made a difference to the 9/11 Commission, trials of accused terrorists and enactments by Congress? Are there any new lessons about the CIA and the quality of US intelligence?
