The Obama administration is moving to relax restrictions on how counterterrorism analysts may retrieve, store and search information about Americans gathered by government agencies for purposes other than national security threats. Attorney General Eric H. Holder Jr. on Thursday signed new guidelines for the National Counterterrorism Center, which was created in 2004 to foster intelligence sharing and serve as a terrorism threat clearinghouse. The guidelines will lengthen to five years — from 180 days — the amount of time the center can retain private information about Americans when there is no suspicion that they are tied to terrorism, intelligence officials said. The guidelines are also expected to result in the center making more copies of entire databases and “data mining them” using complex algorithms to search for patterns that could indicate a threat. 

Intelligence officials on Thursday said the new rules have been under development for about 18 months, and grew out of reviews launched after the failure to connect the dots about Umar Farouk Abdulmutallab, the “underwear bomber,” before his Dec. 25, 2009, attempt to bomb a Detroit-bound airliner. After the failed attack, government agencies discovered they had intercepted communications by Al Qaeda in the Arabian Peninsula and received a report from a United States Consulate in Nigeria that could have identified the attacker, if the information had been compiled ahead of time.
