Incommunicado and Guantanamo
I can think of a dozen reasons why one would not allow outside communications with POWs or enemy combatants, none of them having to do with abuse.
I don't recall POWs--under the Geneva Convention--in ANY war--being allowed either legal representation or unrestricted personal contact with the outside world.
The Red Cross has inspected and visted POW camps for a long time. Including Guantanamo.
