You know, compelling evidence like being a taxi driver or yelling "Allah!" when beaten or something.
Jordanian authorities said Safaa Mohammed Ali, 23, was among the suicide attackers who struck last Wednesday at the Grand Hyatt, SAS Radisson and Day's Inn hotels, killing at least 57 people.
A statement by the U.S. command said someone by that name was detained in November 2004 in connection with the American assault on the insurgent stronghold of Fallujah. The command said it could not confirm whether the person detained was the same man who took part in the Amman attack.
"He was detained locally at the division detention facility" but was released two weeks later because there was no "compelling evidence to continue to hold him" as a "threat to the security of Iraq"
I will point out that at this point we don't know it was the same guy, and we might never know. They dug him out of Fallujah, and if ten percent of the Fallujah stories are true, I wouldn't be surprised if he turned terrorist.
The overwhelming point to all this is that we don't know what the hell we're doing over there, and our not knowing is getting people killed and strengthening Al-Quaeda. We need to get out, now.
