U.S. AGENCIES SEEN AS SLOW TO MOVE ON TERRORISM RISK
Independent auditors at several federal agencies issue new reports criticizing agencies for moving too slowly to confront risks of terrorist attacks, even after Sept 11; say some government departments have been slow to control hazardous materials, to secure buildings and aircraft, to clamp down on unlawful immigrants, to protect vital computers and communications links from attack or to take other high-priority measures; their conclusions demonstrate magnitude of government's task in preventing new terrorist attacks, even as Congress approves billions of dollars to be spent on protecting many federal facilities against such array of possible acts of terrorism; members of Congress vow to use inspector general reports as map in demanding stepped-up governmentwide counterterrorism program; photo (M)
