Factual error: The ferry carrying Ziva and Tony to the aircraft carrier should have the Italian merchant flag, but it has the national one (this flag hasn't got the shield drawn in the middle).
Factual error: During the slow motion sequence in DC, landmarks from Los Angeles are in the background. (00:11:45)
Factual error: There is a flashback scene in this episode, where a young, dejected Abby Sciuto is walking along railroad tracks after failing to give the bear back to Ricki. This scene starts with a shot of the railroad tracks, then pans up to Abby. It can be seen that the rails are laid on concrete sleepers, with modern steel clips holding the rails to the sleepers. Given that the flashback appears to take place when she was at least a couple of decades younger (i.e. the mid-1990s), such modern methods of construction wouldn't have been used. A period-accurate railroad track would have wooden sleepers, spikes and lighter rail. As such, it's obvious that the producers just went to the nearest railroad tracks and filmed the scene there.
Factual error: During the sequence where Bankston and Lee are supposed to make the dead drop of Domino, Adams Tavern, the location of the drop, is shown to be at 2177 Pimmit Drive in Woodbridge Va. The map that is showing the location is geographically correct, but "Pimmit Drive" is actually Horner Road. Also once the action leaves the bar, Lee and Bankston hijack a bus that reads "District Transit Authority". Since they are in Woodbridge, the bus service would be OmniLink. (00:30:20 - 00:38:15)
Factual error: Gibbs has a conversation with the father of the victim at the Tomb of the Unknown Soldier. Something that would not be allowed by the guards of the Tomb. (00:36:50)
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)
Factual error: After Gerald gets back to NCIS HQ, he notes that he wasn't able to drive Ducky's Morgan; a stick. Abby brags about knowing how to drive a stick since she was ten. When asked what she drove that had stick, she answered, "Red '47 Ford half-ton with four on the floor and Bubba riding shotgun." When asked who Bubba was, she answered that he was the best coon dog in Jefferson Parish. If in fact Abby grew up in the city of New Orleans, as stated by McGee in the episode before, the dog would not have been the best coon dog in Jefferson Parish but Orleans Parish. No part of New Orleans is inside the Parish of Jefferson. If it was truly the best coon dog in Jefferson Parish then Abby would have lived in Metarie or Kenner, Louisiana, both of which are inside the parish limits of Jefferson Parish.
Factual error: In the scene on the plane when Tony is going to inject the Epi-Pen, it shows him placing it against her thigh and pushing the trigger. In actuality, an Epi-pen is automatic and he actually pushed the end that the needle comes out of.
Deliverance - S6-E15
Factual error: It is constantly mentioned that the number found at the crime scene is Gibbs' military service number. The Marine Corps stopped using service numbers on Jan. 1, 1972 and since has only used Social Security numbers for identification.
Factual error: Obviously written to make the story interesting, but Gibbs says that the first criminal caught by DNA was a Mafia don in Sicily. Well as anyone interested in forensics knows it was Colin Pitchfork in England.
Factual error: Throughout the show, skyscrapers are consistently shown. The height of buildings in Washington DC is restricted by the Height of Buildings Act of 1910, and there are no buildings taller than 13 stories.
Chosen answer: It is never stated, however she must have been there several years if she is on presidential detail.
