Dispelling Rumors That Became Headlines

Continuing our coverage of the Boston Marathon bombings, we speak with Juliette Kayyem, former Assistant Secretary for Intergovernmental Affairs at the U.S. Department of Homeland Security in the Obama administration.

She's also former homeland security adviser to Massachusetts Governor Deval Patrick, and is very familiar with security arrangements for the Boston Marathon.

She dispels some of the rumors that have become headlines.

For example, the Saudi woman in a hospital being interviewed by police was a victim in the bombing, not a suspect.

Also, reports of a bomb at the John F. Kennedy Library were false. Instead, there was an issue with a generator there.

Reports of multiple explosives at finish line were also false - police say there were only two.
