Each day, thousands of pieces of intelligence information from around the world — field reports, captured documents, news from foreign allies and sometimes idle gossip — arrive in a computer-filled office in McLean, where analysts feed them into the nation’s central list of terrorists and terrorism suspects.
Called TIDE, for Terrorist Identities Datamart Environment, the list is a storehouse for data about individuals that the intelligence community believes might harm the United States. It is the wellspring for watch lists distributed to airlines, law enforcement, border posts and U.S. consulates, created to close one of the key intelligence gaps revealed after Sept. 11, 2001: the failure of federal agencies to share what they knew about al-Qaeda operatives.
