Other mistake: When Director Vance's wife shoots Kai from behind, the bullet passes through her, yet doesn't strike Vance, who is standing directly in front of the North Korean.
Continuity mistake: When Abby and Gibbs determine that the ambulance exploding wasn't an accident, McGee is visible next to Gibbs. He then mysteriously disappears, and a moment later, walks around the ambulance carrying an evidence baggy. (00:08:15)
Plot hole: Season 6, episode 8 ("Cloak"). When Ziva and Tony take the elevator two floors down this takes a full minute. When in a hurry for a call it speeds down, yet for this conversation it (conveniently) took a minute.
Continuity mistake: Episode "Heartland": In the first five minutes of the show, after the guys are beaten up in the alley, when the black guy is laid down on the ground there is a blood stain on The Wall, behind where he was standing. When the other guys go to the white guy's aid the blood stain is gone, for about 3-4 shots. When the NCIS team is there gathering evidence the blood is back on The Wall.
Continuity mistake: While Franks and Gibbs are talking in the diner, Franks' hair goes from being swept back to hanging over his forehead throughout the scene.
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.
