Morning Edition co-hosts Steve Inskeep and David Greene discuss the investigation of Monday's Boston Marathon explosions with Roger Cressey, a former counterterrorism investigator and member of the National Security Council, and NPR's Dina Temple-Raston.
Witnesses to yesterday's Boston Marathon explosions include David Abel. He's a reporter for the Boston Globe. He was at the finish line yesterday afternoon around 3 o'clock, and Mr. Abel, what did you see and feel?
Good morning. I'm Steve Inskeep, with congratulations to Bill Iffrig, who ran the Boston Marathon at age 78. He was approaching the finish line when he saw the explosions. Video footage shows him tumbling down. Mr. Iffrig saw scrambled images, smoke in the air, maybe a fragment of what he thought was a bomb, but he stood up and walked the last few feet to the end. He told the Herald of Everett, Washington: When you've run 26 miles, you're not going to stop there.
