"With his appearance in federal court today, Ahmed Ghailani is being held accountable for his alleged role in the bombing of U.S. Embassies in Tanzania and Kenya and the murder of 224 people," Attorney General Eric Holder said in a press release. "The Justice Department has a long history of securely detaining and successfully prosecuting terror suspects through the criminal justice system, and we will bring that experience to bear in seeking justice in this case."
