The Finger - S2-E14
Visible crew/equipment: Nick goes into a house with a bird inside. As he enters the house, you can see a crew person (with a beard) in the reflection of the frame.
Factual error: When Grissom calls Greg into his office to ask him about his Scandinavian heritage, Greg says his grandfather was kicked out of Norway for getting his grandmother pregnant before they were married. Norway did not kick people out of country for that reason. Anyone who does family research will see that 7 out of 10 times a child was born out of wedlock or illegitimate, and nothing was done about it. It is recorded in the church records and that is it, there were lots of reasons this happened that children were born to unwed parents. Main reason was that they applied to be married and the marriage was disapproved of for one reason or another. Europeans are not as prudish as Americans about this stuff. A lot of Scandinavians nowadays live together, have kids and never get married.
Other mistake: In the first scene when we see Dr Langston from behind as he's watching people passing by he's wearing glasses but when we see his face he's not wearing any. (00:00:15)

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: After Natalie lowers the car onto Sara Sidle we know her right arm is pinned and she cannot move it. When Sara hears the coyotes she starts to look around and see where they are coming from. At one point we can see Sara with her right arm inside the crashed vehicle. (00:22:25)
The Fallen - S14-E19
Factual error: DB Russell gives Mark Roberts a bottle of water to hold. In the blood he leaves his fingerprint on the bottle. Stokes is watching with another policeman the CCTV footage from the interview room. Stokes then says grab a screen shot of the water bottle. They zoom in and low and behold they get a totally clear fingerprint. No way to get that much clarity from a CCTV camera. (00:17:00)
The Fallen - S14-E19
Continuity mistake: Sarah Sidle is talking to Deborah Hughes in the hospital at the end of the episode. Shots from behind Deborah has her ponytail down her back, shots of her front has her ponytail over her left shoulder. (00:39:00 - 00:41:00)
Factual error: At the time where they are looking into the moon and the time, they misstate the time the moon rose in 1997 and they state that the moon was waning, when it actually waxed in the middle of June in 1997. (00:33:00)
Go to Hell - S8-E3
Continuity mistake: After Amy is thrown from the balcony and dies, her eyes are open in one shot and more closed in the next shot after the camera cuts away to a shot of Catherine Willows. (00:41:00)

This includes Limbo and Lust which show the drawings with the women horizontal. The comment "You said he was giving us a show" is made, after which it shows the window pictures again. This time, the drawing of Limbo and Lust show the women vertically. Much later in the scene, they are back to horizontal. (00:28:30)
Continuity mistake: Near the start, when Ray is showing the photograph of Madeline with the security guard to passersby asking if they've seen her and also when he shows it to Nick, we can see the photo Ray is holding out in the wide shots, but in the two closeups of the photograph it's actually a different photo. Then later, when Ray shows the photo to Madeline's mother it's the same as the one from the closeup earlier.
