Inside Gitmo's other secret CIA facility

A few hundred yards from the administrative offices of the Guantanamo Bay prison, hidden behind a ridge covered in thick scrub and cactus, sits a closely held secret. A dirt road winds to a clearing where eight cottages sit in two rows of four. They have long been abandoned. The special detachment of Marines that once provided security is gone.

But in the early years after Sept. 11, these cottages were part of a covert CIA program. Its secrecy has outlasted black prisons, waterboarding and rendition. In these buildings, CIA officers turned terrorists into double agents and sent them home.

It was a risky gamble. If it worked, their agents might help the CIA find terrorist leaders to kill with drones. But officials knew there was a chance that some prisoners might quickly spurn their deal and kill Americans.

For the CIA, that was an acceptable risk in a dangerous business. For the U.S. public, which was never told, it was one of the many secret trade-offs the government made on its behalf. At the same time the government used the threat of terrorism to justify imprisoning people indefinitely, it was releasing dangerous people from prison to work for the CIA.

Nearly a dozen current and former U.S. officials described aspects of the program to the Associated Press. All spoke on the condition of anonymity because they were not authorized to publicly discuss the secret program, even though it ended around 2006.

The program and the handful of men who passed through these cottages had various official CIA code names. But those who were aware of the cluster of cottages knew it best by its sobriquet: Penny Lane.

It was a nod to the classic Beatles song and a riff on the CIA's other secret facility at Guantanamo Bay, a prison known as Strawberry Fields.

When prisoners began streaming into the prison on the U.S. naval base at Guantanamo Bay, Cuba, in January 2002, the CIA recognized it as an unprecedented opportunity to identify sources. That year, 632 detainees arrived at the island. The following year 117 arrived.

"Of course that would be an objective," said Emile Nakhleh, a former top CIA analyst who spent time in 2002 assessing detainees but who did not discuss Penny Lane. "It's the job of intelligence to recruit sources."

By early 2003, Penny Lane was open for business.

Candidates were ushered from the confines of prison to Penny Lane's relative homeyness, officials said. The cottages had private kitchens, showers and televisions. Each had a small patio.

Some prisoners asked for and received pornography. One official said the biggest luxury in each cottage was the bed: It wasn't a military-issued cot but a real bed with a mattress. The cottages were designed to feel more like hotel rooms than prison cells, and some CIA officials referred to them as the Marriott.

CIA spokesman Dean Boyd declined to comment.

Sen. Kelly Ayotte, R-N.H., who serves on the Armed Services and Homeland Security oversight committees, said Tuesday that she was still learning more about the program but was concerned about the numbers of prisoners who were released by the Bush and Obama administrations and returned to fight with terrorists against U.S. interests.

"So, when I juxtapose that to the CIA actually thinking that they can convert these people, I think it was very ill-conceived program for them to think that," Ayotte said on MSNBC's "Andrea Mitchell Reports.

Sen. Bob Casey, D-Pa., said it was difficult for him to evaluate the CIA program's effectiveness. "But it has a degree of recklessness to it that I would be very concerned about," he said.

The U.S. government says it has confirmed about 16 percent of former Guantanamo Bay detainees rejoin the fight against the United States. Officials suspect but have not confirmed that another 12 percent rejoined.

President Obama took an interest for a different reason. Shortly after taking office, he ordered a review of the former detainees working as double agents because they were providing information used in Predator drone strikes, one of the officials said.

Infiltrating Al-Qaida has been one of the CIA's most sought after but difficult goals, something that other foreign intelligence services have only occasionally accomplished. So candidates for Penny Lane needed legitimate terrorist connections. To be valuable to the CIA, the men had to be able to reconnect with Al-Qaida.

From what the Bush administration was saying about Guantanamo Bay prisoners at the time, the CIA would have seemingly had a large pool to draw from. Vice President Dick Cheney called the prisoners "the worst of a very bad lot." Defense Secretary Donald Rumsfeld said they were "among the most dangerous, best trained, vicious killers on the face of the Earth."

In reality, many were held on flimsy evidence and were of little use to the CIA.

Prisoners agreed to cooperate for a variety of reasons, officials said. Some received assurances that the United States would resettle their families. Another thought Al-Qaida had perverted Islam and believed it was his duty as a Muslim to help the CIA destroy it.
