Article Photos: Little sign of Libyan probe into consulate attack 2/2

  FILE - On this Wednesday, Sept. 12, 2012 file photo, a man looks at documents at the U.S. consulate in Benghazi, Libya, after an attack that killed four Americans, including Ambassador Chris Stevens. The graffiti reads, "no God but God," " God is great," and "Muhammad is the Prophet." After more than two months, Libya’s investigation into the attack on the U.S. Consulate in Benghazi appears in limbo. Key security commanders and witnesses say they were never questioned. No suspects have been named, and gunmen who were seen participating in the assault walk freely in the eastern Libyan city. Hanging over the probe is a fear of reprisals from powerful extremist militiamen.(AP Photo/Ibrahim Alaguri, File)
