Camp 7 separates the 15 men from the 262 others, who have found ingenious ways of communicating during five-plus years here.

Tuesday, for example, Camp 5 captives announced the arrival of the weekly media tour by banging on their cells' steel doors and calling to each other in Arabic that ''madaneyeen,'' or civilians, were on the cellblocks.

In contrast, the only two attorneys to see a Camp 7 captive say he has only been able to communicate with one other detainee -- at a recreation time they have shared throughout their confinement.

Even Hamdan's case prosecutor has told the case judge that he doesn't have the necessary clearances to meet with high-value detainees.

Army Col. Larry Morris, the current chief commissions prosecutor, told reporters Wednesday morning that his side hasn't yet ruled out granting permission to Mizer -- who does have top-secret security clearance -- to talk to them.

For his part, Mizer has said he doesn't want to publicize what the United States did to the men. His clearances only allow him to ask questions -- not reveal the answers.

So far, only Wells Dixon and Gita Gutierrez, staff attorneys at the New York Center for Constitutional Rights, have seen a Camp 7 captive -- Khan, a 1999 graduate of Ownings Mills High School in Maryland.

And only a few details of their meetings survived the censor's ink, notably the name of their prison compound, Camp 7, and that the young man has only spoken with one other high-value detainee here -- another captive the CIA admitted waterboarding, Abu Zubaydah.

Neither Khan nor Abu Zubaydah are among the seven men Hamdan's lawyers seek to question in the case, which reconvenes Thursday for hearings ahead of a May trial when the Pentagon will assemble military officers from around the world to sit in judgment of Osama bin Laden's driver.
