A Bullet Runs Through It (Part 2) - S6-E8
Revealing mistake: When the dead Cirque de Soleil investor guy (the one that bled out in Super Dave's body bags) is on the exam table, you can see him breathe twice, despite that his stomach and ribs are cut way open for Doc Robbins autopsy.
Still Life - S6-E10
Revealing mistake: The corpse's eyelids move/blink when the coroner slams the door in the morgue on the season finale of CSI.
Continuity mistake: While Kelly is being interrogated in the interview room by Nick, her hair changes between shots. Close-up it hangs loose. In the wide shots both sides are tucked behind her ears.
Audio problem: Warrick is examining the garage for evidence and sees a stack of crates of soda, he sees one has a bullet hole in it. He picks it up and shakes it, it rattles, demonstrating the bullet is still in the can. He pops the ring to open it and it hisses, despite the fact that the bullet hole in the side would have let the pressure out. They clearly used an unopened can to film the scene.
Factual error: Brown states that silencers are not able to be purchased and are illegal. Not true. A silencer can be legally purchased providing the proper forms are completed with the ATF.
Pirates of the Third Reich - S6-E16
Factual error: The Titan arum, corpse flower, has some problems in this episode. First, the flower grows naturally in the tropical forests of Sumatra. It is not very likely to survive sitting on a bench in the arid desert sun of Nevada. Second, Brown and Stokes track the smell of decomposing flesh to the flowers on the bench. The question is asked who would have a corpse flower besides someone trying to cover the smell of a decomposing body. To start with, none of the plants shown are flowering. The corpse flowers stench comes about when the flower opens. Then there is the rarity of the bloom itself. The botanical gardens around the world with corpse flowers make a very big event out of the bloom. Also, the bloom lasts no more than 36 hours. And then there is the stench of the bloom itself. That stench lasts no more than 8 hours. All this makes it useless to try to hide the smell of dead bodies with this plant and makes it impossible for Brown to state the plants are giving off the odor of decomp.
Visible crew/equipment: When Sofia and Brass arrive at the interrogation room where Dwight is, you can see a red tape mark on the floor outside the door which Louise Lombard promptly glances down at and makes a point of placing her left foot on it. This has nothing to do with the fact that the "Hard Crime" film crew are following them because they're only observing.
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.
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.
