Factual error: At the inauguration party, the band sounds three "Ruffles and Flourishes" and then "Hail to the Chief" for the departure of the President. The President should receive four "Ruffles and Flourishes" prior to "Hail to the Chief", and both are sounded only at his entrance, not his departure.
Factual error: 26,000 people work in the Pentagon. If they were to all file past one person so he can try to pick out a crime suspect, and each person takes just two seconds to walk past, be checked, eliminated and sent on their way, it will take fourteen and a half hours to clear the building. There are going to be some very unhappy people at the back of the queue.
