"Sept. 11 changed everything,' the saying goes. It is striking, however, how much has not changed in the three and a half years since nearly 3,000 people were killed on American soil. The nation's chemical plants are still a horrific accident waiting to happen. Nuclear material that could be made into a 'dirty bomb,' or even a nuclear device, and set off in an American city remains too accessible to terrorists. Critical tasks, from inspecting shipping containers to upgrading defenses against biological weapons, are being done poorly or not at all."
