The Finger - S2-E14

Continuity mistake: Nick counts the bullet holes in the rabbit sign used for target practice and says there are only 9 holes. It shows a flashback to the guy shooting and he shoots a tenth hole in the sign near the rabbit's right arm. This hole is not shown on the sign Nick looks at.
Continuity mistake: When Warrick is talking to Dr. Robins, his collar changes place. During the close-ups, only the right side of his collar is tucked in. During shots farther away, both sides are tucked in.
Continuity mistake: The dead news lady anchor's expression changes between shots from decedent to total shock while Sarah and Russell discuss the case.
Continuity mistake: The son of a CSI is waiting in a hospital hallway. He is sitting on a bench with his elbows on his legs and his hands fisted together on his chin, holding a red jacket. Morgan approaches him, and the next shot shows him with one his left hand across the right leg and the right under his chin. The jacket is also in a completely different position.
Continuity mistake: In the scene where Riley Adams takes a victim's wallet from David Phillips, she takes the wallet with her left hand with no glove on. Next shot Riley has gloves on both hands.
Cats in the Cradle... - S2-E20
Continuity mistake: Marcie Tobin's BMW 7 Series changes from a newer (at the time) E38 model to the first generation E23 when it explodes. Obviously the production couldn't afford to blow up a brand new car so the older model was substituted.
Continuity mistake: When Brass calls Dr. Ray and gets his voicemail instead, Brass raises the phone to his ear twice. (00:02:00)
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: 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.
Continuity mistake: In the opening scene, the female student is wearing green panties. When the two bodies are found, she is wearing red panties. It was a murder behind a locked door, so no one changed them for her.
Suggested correction: The girl had green panties with pink or red strings. When she was found, all that was visible was the string.
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: Stephanie Watson's supposed killer is, on the TV, named as Mark Kelso, but later when Catherine is going over the DNA sample with Greg, it is a match to a Dwight Kelso - supposedly the same person.
Targets of Obsession - S11-E15
Continuity mistake: When Justin Bieber gets shot, we see him from the back as he falls back, and his left hand is flailing around with no gun in it. We then cut to him from the front falling backwards, and he's holding the gun in his left hand the whole way down to the ground.
A Kiss Before Frying - S11-E12
Continuity mistake: Near the end when Greg meets Rita at the bus station, she puts her arms around his neck. The next shot from the front shows her arms and hands on Greg's chest. Rita's arm/hand position changes continually throughout the scene.
Blood Moon - S11-E3
Continuity mistake: When Nick is talking to Catherine about what happened at the night of the murder he folds his arms. In the next show they are unfolded. Although you can't see his arms entirely, it becomes clear from the position of his shoulders and the wrinkle in the middle of his shirt that instantly disappears.
Hitting for the Cycle - S11-E18
Continuity mistake: Series 11, Episode 18, "Hitting for the Cycle": At the very beginning of the episode they are talking about the cycle while looking at the board. The three main ones, Suicide, Accidental and Homicide, are together on cards with a space above and then two more cards. The scene then goes out to show the CSIs again, and there are now four cards grouped together on the board.
Grissom's Divine Comedy - S8-E12
