Nearly eight months after the attack on a U.S. consulate killed four Americans, including the U.S. ambassador to Libya Chris Stevens, no one has been brought to justice. And key questions still remain.

Today, Vice President Joe Biden joined Secretary of State John Kerry in honoring those who were killed in the attack on September 11th... unveiling their names inscribed on a wall at the State Department.

"I wish we didn't need a wall like this. I wish I could tell all of you and all of you brilliant young State Department Personnel up there, I wish I could tell you we're not going to add any more names to this wall. I wish I could say that with certainty." Biden added, "But the truth of the matter is there will be more. There will be more. But with God's guidance and a little bit of luck, there'll be fewer."

But are we relying too heavily on luck? Are we any closer to holding someone accountable for the American lives lost?
