NEW YORK, NY October 19, 2005 —The United States is still holding some 500 prisoners on the Guantanamo military base in Cuba. Only four have been charged. In recent months, some of the prisoners have made news by engaging in a hunger strike.

That news has reached the ears of the public via attorneys who've been visiting the prison camp this past year -- under the leadership of the Center for Constitutional Rights. They are among the few who've gotten to know prisoners - and to review the government's evidence against them.

WNYC's Marianne McCune asked two New York attorneys to take a microphone and recorder along as they work on their cases.
