Factual error: When Red goes to meet Zamani at the Lincoln memorial, he initially walks down the monument steps eastward, towards the reflecting pool in the direction of the Washington Monument and finds Zamani at the base of the steps. The map that is shown of his supposed location in front of the Lincoln Memorial when the FBI starts tracking him, isn't a map of the National Mall, nor the Lincoln Memorial. Later, when they are walking and he is "on the move, heading westbound", they are actually walking away from the Washington Monument, towards the Lincoln memorial, to the location where they had originally met (and discussed the Cherry Blossoms). Two seconds later, they are near 14th St, which is easily a 25 minute walk from the Lincoln Memorial.
Factual error: The FBI logo on the projector screen is not the actual FBI logo. There are supposed to be 3 red stripes and 2 white stripes. There are supposed to only be 13 stars, 6 more have been added next to the scale. There are less than 46 leaves on what are supposed to be Laurel Leaf branches. [The differences can't be intentional, as "unauthorized use" of the FBI seal only applies where a situation might be construed to imply that the FBI approves its use, not the case in a fictional TV program.]
