Visible crew/equipment: At the re-enactment field, after Ziva pulls a gun on the two men in the graveyard, it then cuts to McGee and Tony with Kearns while Gibbs is on his cell. Two shots later, the camera becomes visible on the right side of the screen, just as Gibbs walks past it. (00:40:45)
Continuity mistake: When inside the Smithsonian, Tony is fooling around with a bear. The baseball hats on all 3 agents have black trim on the brim, then white trim, then black trim. Zeva says her hat has a 9mm hole, and pokes a finger through a hat with a black trim. Gibbs says it is for ventilation. Then she drives home, the hats have white trim, and hers has no hole.
