Deliberate mistake: When the runner is shot in the back of the head in the SUV, the bullet has come out the front of his head. However, blood is seen on the windshield instead of a bullet hole where the bullet would have continued to go through the glass.
Other mistake: When Grissom goes to the crime scene to investigate, he finds the worker's drill hanging over the edge, still plugged in. Dropping the drill (35-45 pounds) 5-6 feet (the height of the worker) over the edge would have ripped the plug from the outlet and cause the drill to fall all the way to the ground with the victim. (Grissom barely puts any effort into unplugging the drill when he inspects it).
Continuity mistake: When Sara is showing Greg the route the old woman took in her car, she draws a blue line on the screen with her finger. When she says something about turning left she draws a continuous line to the "Meadows Lane," but when the shot changes and goes back the line is broken into two.
Revealing mistake: At the end of the episode, Grissom pins the newspaper article about the security guard's death onto the bulletin board and the camera zooms in on it. The article is three paragraphs long, however it is the same paragraph of text repeated three times. (A DVD player with a zoom feature can confirm this.) (00:44:30)
Who Are You? - S1-E6
Deliberate mistake: A plumber is looking for a leak under the floor of a house, and sees the bones of a hand sticking out of the concrete wall at the side of the house. The concrete is flat, this is because in construction boards are put up and the concrete is poured in, so how were the fingers sticking out of the boards during construction? In reality, the fingers would be inside the concrete, the workman would see nothing, no plot for CSI.
Factual error: Grissom sees an information card for a 17th century suit of Japanese armour (just the card, not the suit itself), and immediately deduces that the suit must actually be from the 19th century, because the Japanese military was formed in the 1860s. That military was westernised, and did not wear armour. There was nothing on the card that falsely referred to that military as being established earlier, or indicated that the suit belonged to it. There was a reference to the "military class", but that was historically correct, and meant the Samurai.
Factual error: Grissom does a quick analysis on the rough diamonds (chemical or laser) and immediately identifies the region of origin for the diamonds. He and Catherine then postulate that the diamonds are conflict diamonds. There is no way to identify the country or region of origin through any type of analysis. The United Nations and the world's diamond industry are looking for a way. http://www.reliefweb.int/library/documents/conflictdiamonds.htm http://pubs.acs.org/hotartcl/cenear/010212/7907sci1.html http://www.whitefirejewelry.com/wfbb/viewtopic.php?p=88&sid=b0e62206a64d98c81e53b600e053582f.
Revealing mistake: When Grissom finds Isabelle Millander dead in her chair, you can see her blink as the shot changes, even though she's supposed to be dead.
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.
Blood Drops - S1-E7
Continuity mistake: Sara takes pictures of Brenda with an UV light camera. The camera used to film the episode for broadcast is barely able to show the walls in the background as tiled. When the UV pictures of Brenda are used in the interrogation, the photos show Brenda's back up against the tile wall.
Continuity mistake: When Sara and Jim Brass are interrogating Tonya you can see Jim open up her cell phone behind Tonya. Than they do a wide shot and Jim opens up the phone again.
Continuity mistake: When Catherine tells Grisson she liked the tough act (while listening to the guy testify) he said too much, she said not enough. Then he glances over at her. The guy is talking, which indicates a continuous line, even though the shot changes, but Grissom is not looking at Catherine during the shot change, instead he's got his head leaning against the glass.
The Execution of Catherine Willows - S3-E6
Continuity mistake: At one point Catherine is at the coffee shop and the parents of a murdered girl come to talk to her. She is holding her coffee in the right hand and her cell phone rings and she grabs it with her left. The shot switches angles while Catherine is talking and her cell phone has magically shifted to her right hand.
Continuity mistake: When Sara and Warrick are looking at the dead girl in the prom dress, she is turned over by the coroners and her hands are almost touching straight above her head. But when the shot changes, her arms have moved quite far apart.
Continuity mistake: When Sara is waiting with Greg for the results for what was inside the tyre that exploded, she grabs the paper straight off the printer, reads it, looks at Greg and takes off immediately to inform Gil. When Grissom looks at the paper, you can see Greg's name is signed at the bottom as confirmation, but he never got anywhere near the paper.
Revealing mistake: In the scene where the CSI team first arrive at the crime scene and Grissom is taking photos, the first photo he takes, you can see that the victim's eyelids flutter a bit and his belly is seen contracting, a clear sign of breathing.
Continuity mistake: When Catherine walks up the stairs, Horatio Caine aims his gun upwards. In the next shot he has his arms down. (00:36:10)
Continuity mistake: When Gil and Catherine catch the couple in the bedroom, they are all sitting in the living room. Amanda is drinking a soda and it is about half full. Gil then asks for the straw. When we look at the soda again, it's full.
The Good, the Bad, and the Dominatrix - S7-E23
Other mistake: In episode "The good, the Bad and the Dominatrix" When the night watchman is found dead, they say he was shot in the back, there is no bullet hole in his coat.
