Credibility of Government’s Top Witness Questioned in Mumbai Terror Case

Defense attorneys for a Chicago businessman accused in the 2008 Mumbai attacks are trying to undermine the credibility of an admitted terrorist who is serving as the government's star witness.

David Coleman Headley returns to the witness stand Tuesday to face questions from defense attorneys for Tahawwur Rana. He's accused of helping Headley, his longtime friend, lay the groundwork for the attacks that left more than 160 people dead in in India's largest city.

Headley has already pleaded guilty and agreed to testify against Rana, who is accused of providing a cover as Headley conducted surveillance for the attacks.

Rana's attorneys say Headley's testimony isn't credible because he's lied in the past. They went after his credibility last week, and told a judge they're just getting started.
