It had to happen eventually. Early Tuesday morning, Ahmed Khalfan Ghailani became the first Guantanamo Bay detainee to set foot in the U.S. The Tanzanian native had been held in Gitmo since 2006 on charges of his alleged involvement in the 1998 bombings of the U.S. embassies in Tanzania and Kenya. Ghailani is expected to make his first court appearance in Manhattan on Tuesday, where he'll face 286 counts of murder, conspiracy to murder, bomb, and maim, and conspiracy to use weapons of mass destruction against U.S. nationals. The March 2001 indictment against him also alleges that he conspired with Osama bin Laden and other members of al-Qaeda to kill Americans. If convicted, Ghailani could face the death penalty.
