According to the NYTimes this is what the crowd is saying:
“I swear, he’s dead,” one Libyan says, peering in.

“Bring him out, man! Bring him out,” another says.

“The man is alive. Move out of the way,” others shout. “Just bring him out, man.”

“Move, move, he is still alive!”

“Alive, Alive! God is great,” the crowd erupts, while someone calls to bring Mr. Stevens to a car.
