Another suicide attempt by a detainee. Unsuccessful. Unfortunately.

A Guantanamo Bay prisoner slashed his throat with a sharpened fingernail last month, spilling a lot of blood but surviving, a U.S. military commander said Tuesday.

Guards administered first-aid and took the prisoner to the prison clinic, said Navy Cmdr. Andrew Haynes, the deputy commander in charge of the guard force.

"There was an impressive effusion of blood," Haynes told reporters visiting the base. He would not disclose the man's name or nationality. A medical officer, who could not be identified under military rules for journalists, said the prisoner received several stitches and spent a week under psychiatric observation.

There have been four suicides since the U.S. opened the military prison at Guantanamo in January 2002 for men suspected of involvement in terrorism or links to al-Qaida and the Taliban.

I know we have to treat these guys humanely. I know we have to give them medical care. And I know the fact that we do both is part of what separates the United States from our enemy.

But I still can't help but feel that the only good terrorist is a dead terrorist.
