Actually, Fast and Furious has killed (and still kills) lots more people, but I get where you're coming from.
Actually, no. Stevens was running guns, ManPADS, and other light infantry weapons from Libya, through Turkey, and into Syria, where a LOT more people have died than in Fast & Furious.
That's the big story here, because not only was Zero trying to keep the meme alive that "Al Quaida is dead; Libya is progressing toward being a normal country," he was trying to keep the news from coming out that he is quite deliberately keeping AQ alive and kicking, as they surround Israel with jihadis armed to the teeth with American weapons.
