Continuity mistake: Agent Todd is standing there coat open, hands in her pockets on Air Force One watching Gibbs walk away when the bad guy who is a reporter (Leonard) comes up to her and comments "Loosening your dress code Kate". Seconds later when she turns to indicate that he should return to the press section her coat is now buttoned up.
Continuity mistake: At the naval base Gibbs is talking about the Marine taking his bike up into the mountains and blasting country music. The person he is talking to has their arms down by their side until the camera changes. They are then behind his back.
