How will the killing of a U.S. General impact President Obama's plans to wind down the war in Afghanistan?

An attack in Afghanistan today claimed the life of U.S. Army Major General Harold Greene. He was shot and killed in a shooting that left more than a dozen other coalition forces wounded. Maj. Gen. Greene is now the highest ranking American killed in wartime since Vietnam. This is just the latest case of a member of the Afghan security forces opening fire on Americans working with them. Randi Kaye looks at the history of these 'green–on–blue' attacks.

Afghan soldiers often need to work side by side with American forces. Who is responsible for vetting them and is enough being done to protect the Americans? Anderson discussed this with CIA and FBI counterterrorism veteran Philip Mudd, along with Retired Air Force Lieutenant Colonel Rick Francona, who was a target of a ‘green–on–blue’ attack.
