Factual error: Lieutenant Colonel Mann explains to the NCIS team that a "99 Toyota" is the only unaccounted for vehicle from the golf course bombing. The vehicle is a Toyota but is obviously a mid-80's Corolla, with the last production year being 1987, making it over a decade older than Mann claims. Additionally, she would not have know the year of the vehicle prior to the team running the plate, nor would she have pointlessly assumed its year. (00:32:06)
