The Finger - S2-E14
Continuity mistake: When Catherine goes into the diner with a man and Sarah is sitting talking to her date, in one shot they are talking and in the next immediate shot he has a cup to his lips.
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.
Revealing mistake: In the shot looking across the four monks in the autopsy room, you can see the one closest to the camera taking a deep breath.
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.
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.
Factual error: The CSI crew set up an experiment. They put some chloroform into the tire, set the bus on a dynamometer (or some other testing platform) and wait for the tire to fail. The tire fails in the experiment in the exact same amount of time as it did in real life. Problem: They have no idea how much chloroform was used and it would be impossible to match it by luck. More chloroform used would equal quicker failure. Then, there is the heat. The tire traveling over the hot asphalt road would build heat faster then on their testing platform. More heat would mean a quicker failure, too.
Factual error: Sara calculates the time needed to sabotage the tire at a minute to a minute and a half. That is, remove the valve core, allow the majority of the air to escape (cannot pour anything into the tire while the air is escaping) pour in enough chloroform to sabotage the tire, replace the valve core, and air the tire to pressure. Even with an industrial air compressor, it would take over 2 minutes to air that tire to full pressure.
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.
Cats in the Cradle... - S2-E20
Deliberate mistake: A father, daughter (both construction\demolition experts) and the boyfriend try to frame the husband for attempted murder by planting a pipe bomb in her (wife\daughter\girlfriend's) car. The bomb is a stick of dynamite inside a pipe with 2 endcaps on it. A pipe is used to hold a improvised munition together: i.e., homemade explosives, or something like Anfo. The pipe provides the casing for the explosive material. Or, it is used to keep the shrapnel fragments around the explosives (like nails or pellets around a stick of dynamite). For dynamite, you simply drill a hole (in rock, in concrete, in whatever.) and drop the stick in. It needs no extra casing. The family would have known that. But the CSI crew needed some evidence to analyze and the blasting cap + detonator circuit would have given them nothing to study. The endcap with the hole drilled for the blasting cap was the case solver.
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 Catherine walks up the stairs, Horatio Caine aims his gun upwards. In the next shot he has his arms down. (00:36:10)
Revealing mistake: As they recover the car from the canal and open the door to reveal the girls dead mother, you can see her still breathing as they lie her on her back to examine her.
Revealing mistake: When the CSI from Miami and Catherine are in the autopsy, the guy goes to take a sample from the eyes of the dead woman. When he moves the swab towards her eye, you can see the actress' top eyelid move instinctively. She's supposed to have been dead for hours.
Continuity mistake: In this episode, Catherine is sent to Miami on a lead of a missing child. There they find a car in a swamp, and when the pull the car out and open the door, a female body falls halfway out. When this happens you can see the woman playing the victim breathing. You see her stomach moving up and down.
