Navy NCIS: Naval Criminal Investigative Service (2003) - 6 mistakes in whole show

Continuity: 5-4: Identity Crisis. When Ziva is speaking with McGee her lapel changes from being turned up and laying down.

Plot hole: Season 6, episode 8 ("Cloak"). Ziva and Tony enter the secure facility by entering a pass code they obtained by watching the guards enter it previously. Once inside, they open another door using a pass code. How did they know that code? It would make no sense to have both locks use the same code, rendering the second door useless.

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.

Other: Season 5, Episode 12, "Stakeout": The picture on McGee's camera phone is just wrong. It shows not just the man in front of him, but it also shows a hand, holding a camera phone - McGee's camera phone. In other words, the phone is showing a picture of itself and the man, instead of just the man.

Continuity: While Tony and Ziva are outside Ziva's apartment eating pizza, Ziva is eating the pizza in one shot with the slice in the shot, in the shot directly before this and directly after, the pizza is no where to be found and she is no longer chewing.

Continuity: 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.
