From New York Times Guantanamo specialist William Glaberson, providing a little insight on the highly complicated case and journey of Salim Ahmed Hamdan:

GUANTÁNAMO BAY, Cuba — A panel of six military officers convicted a former driver for Osama bin Laden of a war crime Wednesday, completing the first military commission trial here and the first conducted by the United States since the end of World War II.

But the commission acquitted the former driver, Salim Ahmed Hamdan, of a conspiracy charge, arguably the more serious of two charges he faced. His conviction came on a separate but lesser charge of providing material support for terrorism.
