From Yahoo! News :
Obama was heckled at length by Medea Benjamin, co-founder of the anti-war group Code Pink and a leading (and highly recognizable) critic of the so-called war on terrorism.
"Can you tell the Muslim people their lives are as precious as our lives?" she shouted as she was finally ushered from the hall. "Will you apologize to the thousands of Muslims that you have killed? Will you compensate the innocent family victims? That will make us safer!"
After trying and failing several times to get her to sit quietly, Obama went off script and enlisted her protest to reinforce his message about the need to close the Guantanamo facility.
"The voice of that woman is worth paying attention to," the president said, to applause. "Obviously, I do not agree with much of what she said. And obviously she wasn’t listening to me and much of what I said. But these are tough issues. And the suggestion that we can gloss over them is wrong."
Leading up to President Barack Obama's formal address on the drone war, it was revealed that President Obama has used drones to kill at least four Americans.
Ms. Benjamin, in her remarks made later to AOL/Huffington Post, said that the Obama administration has been playing prosecutor, judge, jury, and executioner.
One of the demands Ms. Benjamin made was to call for the removal of the controversial drone program from the secret operations of the Central Intelligence Agency.
