Built to Kill (Part 1) - S7-E1
Continuity mistake: Series 7 - Part 1: When Sara and Warrick are at the table discussing the case, Sara's box containing her veggie sandwich changes position depending on whether the camera is looking at her or Warrick. (It moves from directly in front of Sara, and then several inches to her right toward the edge of the table).
Built to Kill (Part 1) - S7-E1
Continuity mistake: When Doc Robinson is checking the mouth of the suicide victim, when he opens the mouth you see a chipped tooth on the bottom middle, when they show the zoom in to see the sesame seeds there is no chip.
Built to Kill (Part 1) - S7-E1
Revealing mistake: During Katherine's visit with Dr. Robbins, they are overlooking Suicide Guys' body, discussing his autopsy. Just as the doc's hand touches the corpse's mouth, the corpse's lower lip twitches slightly.
Built to Kill (Part 1) - S7-E1
Revealing mistake: When Sarah visits Dr. Robbins to get an update on Suicide Guy, who is being autopsied, the camera moves to the right and you can see Suicide Guy breathe twice, even though he's supposed to be dead.
Continuity mistake: When the fannysmackers attack Greg, they smash his car back window out. The next morning, when Warrick and Nick are processing the scene, Greg's car window is completely intact.
Post Mortem - S7-E7
Continuity mistake: When the woman first falls through the glass, she obviously breaks it all, toward the bottom of the window. Then her position changes and there is cracked glass in place. We then see several more shots of the dead woman, none of which have matching blood spatter or position of her body.
Continuity mistake: When the victim is hit by the car, it shows him get run over by the front right wheel of the limo. Later on, the body is "thrown 45 feet" and is ahead of the stopped limo.
Revealing mistake: Mickey Dunn is played as a young man by Rik Young with hazel eyes. His eyes are much darker than the older Mickey Dunn, played by Roger Daltrey. Roger Daltrey's eyes are notoriously as 'blue as the sky'.
Visible crew/equipment: You can see the reflection of the filming car on Mickey Dunn's car just before he is arrested.
Other mistake: When the kid Billy is recounting the murder scene, he states the killer grabbed a cookie from within the cow cookie jar. When Katherine lifts the lid afterwards, we see bloody fingerprints up inside the top, instead of on the lid. Indicating the killer had to have carelessly reached inside the cookie jar with his fingertips, which would have been impossible.
Revealing mistake: The elements of the miniature crime scene are not glued. They should not be in their respective locations, but all over the floor of the miniature.
Factual error: In the scene where Hodges describes the camera glass to Grissom, he states that camera lenses are curved on one side and flat on the other for a higher refractive index. The refractive index is a property of the glass and has nothing to do with its shape. Also lenses used in cameras can have any shape to them, with even a moderately good lens in a compact camera being made of several pieces of glass with few flat surfaces. This is not modern technology in camera lenses, they have been made like this for decades. Narrowing it down to a non-compact camera by Nikon, Canon or Leica is also wrong, as all manufacturers use these techniques.
Other mistake: When CSI Brown is with the mother of the alleged victim, he shows her a picture of the deceased and asks if she knows her. The name on the picture is the one the mother gives (Simone Molinez). How would the correct name be in the picture if the victim had yet to be identified? (00:17:35)
Continuity mistake: The short-haired brunette wannabe Lab Tech has a disappearing and reappearing necklace during her conversation in the lab with Warrick.
Revealing mistake: As the phone number 702-555-0192 is supposedly dialed, you can hear in the sound overlay that the last two digits dialed on the touchtone keypad were the same two digits. Then it shows a close-up of the cell phone dialing the above number.
Continuity mistake: When Brass is interrogating the bartender, there is a cup of coffee in front of him. In the next shot of the bartender's face, the cup is gone. It reappears later on in the scene in a shot from the side. (00:27:00)
Continuity mistake: In the scene just after Hodges and Greg find the seafood they were hunting for in the "Pleasure Providers'" stations or whatnot, Hodges collects a sample of the shrimp by cutting off a little piece. He picks it up with his fingers. In the very next frame, the shrimp piece is in tweezers. Lightning speed. (00:30:55)
Continuity mistake: Outside the brothel, there is an orange post next to the old man's trailer. Suddenly, it is gone in the second scene where the old man is approaching. In the third scene there is one again, but this time it is an orange cone instead of an orange post.
Visible crew/equipment: The prostitutes take turns telling their stories to Captain Brass in their dressing room. But as the long-haired brunette lady tells her story from a distance, you can see a cameraman in the mirror behind her waiting for his turn to film. When she is shown close up, you can see him closer in the mirror, filming.
Continuity mistake: As Brass interviews people at the whorehouse, the curtains switch back and forth several times between shots: pulled back with no light, then stretched out with the sun behind them. They keep switching back and forth.
Answer: He doesn't have the authority to arrest him - when anyone is arrested in the show, a police officer does it. Also he tells Ty that he is going to be submitting his case findings to Ty's insurance company, who would no doubt contact the IRS, who then would have him arrested for fraud etc.
