Two testified in secret -- a psychologist at the Army's Special Operations Command and an Army lawyer with the U.S. Special Forces.
And two former CIA captives testified on paper that had been censored of intelligence secrets. One was an alleged 9/11 mastermind who said that, as a self-confessed terrorist, Hamdan was no terrorist.
Even Hamdan spoke to the jurors for a few moments in a secret session. Lawyers said he described an offer he made to his U.S. captors in Afghanistan. Mizer mysteriously called it a ``squandered opportunity.''
He was the first Guantánamo detainee to successfully argue he had been abused in U.S. custody.
His lawyers persuaded the trial judge to discard evidence they got from him in Bagram, Afghanistan.
His case afforded the first glimpse at war crimes trial of a Gulf Arab who answered a call to jihad.
Hamdan first went to Afghanistan in 1996 not to become Osama bin Laden's driver, but en route to Tajikistan, to answer a sheik's call to defend Muslims from post-Soviet oppression, a story-line likely to be repeated at future tribunals.
NEXT ON THE LIST
Next up for trial is another alleged jihadist who straddled both worlds, Toronto-born Omar Khadr whose father allegedly ran philanthropic fronts for al Qaeda and raised his sons with radical Islam teachings.
He allegedly threw a grenade that killed a Special Forces soldier in a July 2002 firefight in Afghanistan.
The Pentagon's chief war crimes prosecutor, Army Col. Lawrence Morris, acknowledged the historic nature of the Hamdan trial, and welcomed the world's scrutiny.
But he predicted that interest would wane as the Pentagon proceeded with some 80 proposed cases.
Twenty men have so far been named for trial, many of them foot soldiers, but seven whom face proposed military execution.
Some day, he said, trials at Camp Justice would become as commonplace as the journeys of the A's space shuttle.
'At some point you look and somebody asks, `Is there a space shuttle orbiting or not?', '' the colonel said. ``And you don't know anymore because it's no longer an extraordinary event.''
