A government database, which serves as a repository for raw intelligence about terrorist suspects or their associates, has nearly doubled in the past five years to include 1.1 million people by the end of last year,
According to data by the National Counterterrorism Center, the same database, known as the Terrorist Identities Datamart Environment (TIDE), contained about 560,000 names at the end of 2009, following the failed Christmas Day attempt to blow up a commercial airliner over Detroit.
Of the 1.1 million identities in the updated database, about 25,000 are U.S. citizens or legal permanent residents, according to the updated records, says a USA Today report.
The database is a product of the National Counterterrorism Center, which was established in 2004 as an arm of the U.S. intelligence network to better share information across government agencies.
Intelligence sharing was a key weakness highlighted by the 9/11 Commission in its review of government operations in advance of the 2001 terrorist attacks.
