Attorney James Connell has visited his client inside the secret Guantanamo prison complex known as Camp 7 only once, taken in a van with covered windows on a circuitous trek to disguise the route on the scrub brush-and-cactus covered military base. Connell is allowed to say virtually nothing about what he saw in the secret camp where the most notorious terror suspects in U.S. custody are held except that it is unlike any detention facility he's encountered. It's much more isolating than any other facility that I have known," the lawyer says. "I've done cases from the Virginia death row and Texas death row and these pretrial conditions are much more isolating." The Camp 7 prison unit is so shrouded in secrecy that its location on the U.S. base in Cuba is classified and officials refuse to discuss it. Camp 7 has never been part of the scripted tours of Guantanamo offered to journalists and there are no published photos. It's not even mentioned on a military media handout about the detention center. Military officials, while insisting that they adhere to international human rights standards, refuse to describe Camp 7. A few facts have come out through government reports and court testimony. It apparently holds 15 of the 154 prisoners at Guantanamo. The men are apparently held in solid-walled cells - as opposed to the cage-like structures used soon after the U.S. began using Guantanamo as a prison in 2002 - that are intended to limit their ability to communicate with each other. The secret camp also is apparently falling apart.
