Agent Afloat - S6-E2
Character mistake: McGee seeks Director Vance's permission to hack into the Sea Hawk's computer system. He says that in the past four months, he hasn't worked any crime scenes, etc. This is incorrect, as near the start of the episode, he and Ziva go to an officer's home to advise his wife that he is missing. They discover her murdered and then the team, including McGee, are working the crime scene.
Character mistake: At the start, Kort takes the gun from one guy and uses it. He then places it at the second man's body without wiping it for prints. When he swaps his gun though, he wipes it for prints. Why didn't he wipe the first gun he used? (00:00:50)
Chosen answer: "Policing your brass", means to pick up your expended shell casings, after firing your rifle, or pistol.
