Continuity mistake: When Gibbs shows Cpl Yost the tape in the interview room, he is burning a match down to his fingers. Camera shows a closeup of the head of the match being extinguished, but it is just the head that is alight. It is not burnt to his fingers. It also goes from horizontal to vertical.
Continuity mistake: The security guard at the start goes to grab his gun and keeps his hand on his holstered weapon. When Gibbs gives the OK, he now has a handheld metal detector in his hand. In the shot showing Gibbs we can see the guard and he doesn't move.
Continuity mistake: In the scene where Gibbs' phone breaks, and he tells McGee to "reboot" it, Tony is in the back, getting a phone out of the cabinet. He starts to give the phone to McGee. The next shot, the cabinet opens again, and Tony pulls out the phone again and gives it to McGee.
