Lawrence Di Rita, spokesman for Defense Secretary Donald H. Rumsfeld, told reporters that U.S. investigators had re-interviewed the unidentified prisoner on May 14.
“He has said it didn’t happen,” Di Rita said.

If I remember correctly, victims released from the Abu Ghraib facility in the wake of the unauthorized photography incidents were required to sign a statement saying they had been treated humanely and would not discuss the matter further subsequent to their release.
I don’t know what the Guantanamo victims were required to sign, but it would appear that Washington is taking a tough stance on violators, and we can expect more chatty victims to respond to re-interrogation as promptly and definitively as this one has.
