One week since Libyan consulate attack and no answers

The horrific attack in which Ambassador Chris Stevens and three other Americans were killed at the U.S. consulate in Benghazi. Libyan officials have not arrested anyone directly linked to the attack.

The Libyan government is focused on members of an Islamist militia that is sympathetic to al-Qaeda, but the arrests so far are mostly of people who were outside the consulate that night, but not accused of the brutal attack.

CNN's Arwa Damon has been fighting for answers and she's in Benghazi where we asked her how the investigation is going.
