Getting Off - S4-E16
Continuity mistake: When Jamal is been helped out of Ed Burnell's wrecked BMW 7 Series, the wrecked car is a late 80s-early 90s E32 model. However when Burnell was driving it at the beginning of the episode, it was a newer late 90s-early 00s E38 model. Again, the production crew couldn't afford to wreck a brand new car so an older one was substituted.
Continuity mistake: The Camaro at the crash scene is a late second generation model (built from 1970 - 1981), however in the flashbacks to the crash it's a third generation car (82 - 92). The difference in body styles is quite pronounced.
Continuity mistake: When Brass is searching for Ellie's car on his in-car computer, it identifies it as a 1976 Camaro, however when he spots it and calls for back up, he says it's a '78 Camaro. Additionally, the licence plate is also different to what was listed on the computer.
Continuity mistake: When Nick asks Dr. Ray what he's doing out on the Strip instead of at their crime scene, and Ray shows him the photograph of Madeline Briggs, his hand moves from the top of the photo to the bottom in consecutive shots. (00:03:20)
Continuity mistake: When Hodges shows Dr. Ray and Nick the information from Dede Chase's cell phone, Ray's arms change position between shots from the tabletop in front of him to crossed across his chest. (00:08:55)
Targets of Obsession - S11-E15
Continuity mistake: Watch the back angle of McCann getting shot. His gun disappears only to reappear in the front angle.
Targets of Obsession - S11-E15
Other mistake: In the shot right after Stokes shoots McCann you can see that Stokes' SW99 has jammed, with a casing sticking out of the chamber.
Other mistake: When Grissom's vehicle is shown driving to Jackpot, Nevada, he is shown to be driving on the wrong side of the road. (00:03:15)
Living Doll - S7-E24
Revealing mistake: Grissom and Brass enter the darkened apt. and Grissom spots another doll figurine on the book shelf as Brass takes notice of the dead guy on the bathroom floor. As Grissom comments on this being yet another 'miniature killer' scene, the cam flips to a shot of Dead Guy and he wiggles just slightly, even though he's supposed to be dead.
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: Season 10, episode 3 "Working Stiffs": The picture of the employees holding a sign at work with the X's through them at Paulie's house changes between two completely different photos when far away vs. up close.
Visible crew/equipment: At the beginning during the robbery, you can see a boom operator in the glass when the woman grabs her son.
Visible crew/equipment: You can see the reflection of the filming car on Mickey Dunn's car just before he is arrested.
Continuity mistake: Season 9, episode 3 "Art Imitates Life": When J. Skaggs is being interrogated by Brass he has his hands on his lap. In the next shot they are both on the table.
Character mistake: When Catherine slams the trash can lid shut outside and heads to the car to answer her phone, she tells her Mum 'Catherine threw something out', referring to Lindsay.
Character mistake: At the end of the episode when Grissom puts the news clipping up, the word "sacrificed" is spelled as "sacraficed" in the article.
Plot hole: Amanda Haynes is Lacey Duvall's murderer, however in the opening scene she was kissing Patrick Haynes at the party downstairs at the exact time Lacey fell into the pool. She could not have pushed Lacey upstairs. (00:01:16 - 00:41:29)
Living Doll - S7-E24
Factual error: When Nick and Katherine are examining the bloody prints in the bathroom, Katherine looks at the wall outlet and says there are no burn marks present, when smudges are visible around the socket, and the wall next to it.
Revealing mistake: Throughout varied episodes you can see the cadavers breathe while on the examining table.
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.
