Character mistake: At the meeting in Washington the general says nothing more frightening than a soldier with his M16A1, but they were using M16A2s.
Factual error: In the scene after the bombing of the FBI Building there are a couple of firefighters with NYFD on the back of their coats. The New York City Fire Department uses official initials of FDNY for Fire Department New York, not NYFD.
Factual error: In the movie, the FBI's staging area/headquarters for the terrorist cell investigation is at 1 Federal Plaza in New York City. In reality 1 Federal Plaza is the address of the US Court of International Trade. 26 Federal Plaza is the address of the FBI's New York office.
