Revealing mistake: At the crime scene we see Gibbs making notes on his notepad prior to Ducky calling him over. When he's looking at the business card you can see his notes in his notepad. However his notes are all just random lines and squiggles. It's not the case that he's made notes for himself in his own writing style. (00:04:00)

Visible crew/equipment: During the exterior scenes in Arizona, with Sheriff Boyd, Gibbs, and Tony, in some shots either a hidden lavalier microphone or transmitter is visible. One example, when Dina fires her weapon Gibbs dismounts his horse, and his hidden transmitter is briefly seen at his back. Another example, while Dina tells Gibbs and Tony that her doctor ran blood tests, Sheriff Boyd's mic is visible under his shirt by the buttons, and so on. (00:35:30)
Visible crew/equipment: When Gibbs informs Dina Risi of Patterson's death, it then cuts to Dina as she tells them she mixes her own pigments, and in the next shot facing Dina, the wheel base of filming equipment is visible on the right side of the screen (non-existent in overhead long shots). (00:36:05)

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)
