Despite concern about rendition, Obama's prohibition of many other counter-terrorism tools could prompt intelligence officers to resort more frequently to the "transitory" technique.
The decision to preserve the program did not draw major protests, even among human rights groups. Leaders of such organizations attribute that to a sense that nations need certain tools to combat terrorism.
"Under limited circumstances, there is a legitimate place" for renditions, said Tom Malinowski, the Washington advocacy director for Human Rights Watch. "What I heard loud and clear from the president's order was that they want to design a system that doesn't result in people being sent to foreign dungeons to be tortured -- but that designing that system is going to take some time."
Malinowski said he had urged the Obama administration to stipulate that prisoners could be transferred only to countries where they would be guaranteed a public hearing in an official court. "Producing a prisoner before a real court is a key safeguard against torture, abuse and disappearance," Malinowski said.
CIA veterans involved in renditions characterized the program as important but of limited intelligence-gathering use. It is used mainly for terrorism suspects not considered valuable enough for the CIA to keep, they said.
"The reason we did interrogations [ourselves] is because renditions for the most part weren't very productive," said a former senior CIA official who spoke on condition of anonymity because of the sensitive nature of the subject.
The most valuable intelligence on Al Qaeda came from prisoners who were in CIA custody and questioned by agency experts, the official said. Once prisoners were turned over to Egypt, Jordan or elsewhere, the agency had limited influence over how much intelligence was shared, how prisoners were treated and whether they were later released.
"In some ways, [rendition] is the worst option," the former official said. "If they are in U.S. hands, you have a lot of checks and balances, medics and lawyers. Once you turn them over to another service, you lose control."
In his executive order on lawful interrogations, Obama created a task force to reexamine renditions to make sure that they "do not result in the transfer of individuals to other nations to face torture," or otherwise circumvent human rights laws and treaties.
