For Technology Podcast #84, we're going to give you on update on the National Security Agency's domestic spying program. This week, behind mostly closed doors, NSA and other Bush Administration officials provided detailed technical and operational information about the surveillance program to intelligence committees in both the House and Senate. We look into the history of domestic surveillance in the United States, and what technologies were used. Also, an extended discussion with The World's Quil Lawrence, who is freshly back from Iraq. We talk war tech of all stripes, and give you a taste of what it's like for a foreign correspondent to file on deadline.
