Did members of Libya's Security Forces reveal the Ambassador's location?

CBS is reporting that indeed, they did:

Wanis al-Sharef, a Libyan Interior Ministry official in Benghazi, said the four Americans were killed when the angry mob, which gathered to protest a U.S.-made film that ridicules Islam's Prophet Muhammad, fired guns and burned down the U.S. consulate in Benghazi.
He said Stevens, 52, and other officials were moved to a second building - deemed safer - after the initial wave of protests at the consulate compound. According to al-Sharef, members of the Libyan security team seem to have indicated to the protesters the building to which the American officials had been relocated, and that building then came under attack.
Stevens, 52, was the first U.S. ambassador to be killed in the line of duty since 1979. A Libyan doctor who says he treated Stevens told the Associated Press Wednesday that the diplomat died of severe asphyxiation and that he tried for 90 minutes to revive him.
Ziad Abu Zeid said Stevens was brought to the Benghazi Medical Center by Libyans Tuesday night with no other Americans, and that initially no one realized he was the ambassador. Abu Zeid said Stevens had "severe asphyxia," apparently from smoke inhalation, causing stomach bleeding, but had no other injuries.

Not exactly the way Hillary reported events in this CNN piece:

"The mission that drew Chris and Sean and their colleagues to Libya is both noble and necessary, and we and the people of Libya honor their memory by carrying it forward. This is not easy," Clinton said. But she added, "We must be clear-eyed even in our grief."
"This was an attack by a small and savage group, not the people or government of Libya. Everywhere Chris and his team went in Libya, in a country scarred by war and tyranny, they were hailed as friends and partners. And when the attack came yesterday, Libyans stood and fought to defend our post. Some were wounded. Libyans carried Chris's body to the hospital, and they helped rescue and lead other Americans to safety."

Let's see if the truth will reign supreme in the coming days.
