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.
Factual error: Brown states that silencers are not able to be purchased and are illegal. Not true. A silencer can be legally purchased providing the proper forms are completed with the ATF.
Continuity mistake: While Kelly is being interrogated in the interview room by Nick, her hair changes between shots. Close-up it hangs loose. In the wide shots both sides are tucked behind her ears.
Pirates of the Third Reich - S6-E16
Factual error: The Titan arum, corpse flower, has some problems in this episode. First, the flower grows naturally in the tropical forests of Sumatra. It is not very likely to survive sitting on a bench in the arid desert sun of Nevada. Second, Brown and Stokes track the smell of decomposing flesh to the flowers on the bench. The question is asked who would have a corpse flower besides someone trying to cover the smell of a decomposing body. To start with, none of the plants shown are flowering. The corpse flowers stench comes about when the flower opens. Then there is the rarity of the bloom itself. The botanical gardens around the world with corpse flowers make a very big event out of the bloom. Also, the bloom lasts no more than 36 hours. And then there is the stench of the bloom itself. That stench lasts no more than 8 hours. All this makes it useless to try to hide the smell of dead bodies with this plant and makes it impossible for Brown to state the plants are giving off the odor of decomp.
Revealing mistake: At the end of the episode when Grissom and Archie are listening to the tape from Nick's kidnapping, the screen shows the audio being played. While the audio obviously changes, the lines that sketch what the sound would "look" like don't. In order for the sounds to be different, the lines would have to change too.
Factual error: In Kiss-Kiss,Bye-Bye, Stokes and Brown are watching surveillance footage when a Trans-Am pulls up on screen. They are able to get the license plate number and when they pull it up, the computer says it is a 1978 Trans Am. When looking at the rear end of the car on screen, it is from a 1979-1982 model where the licence plate was placed on the rear bumper. The 1978 model had the license plate mounted between the taillights.
Factual error: The CSI staff repeatedly refer to the murder weapon as a tire iron. It is a crow bar or demolition bar. It had a nail pulling head, not a socket for the lug nuts.
Room Service - S6-E2
Continuity mistake: When Warrick is in the hotel room at the start, the corpse's eyes alternate between open and closed.
A Bullet Runs Through It (Part 1) - S6-E7
Other mistake: "A Bullet Runs Through It," part 1; while Catherine is in the lab reviewing the audio tape of the police call to dispatch, the dispatcher claims that the first call she received was at 6:34. First, her lips do not match what she is saying and then when they show the screen with the audio playing, the screen reads "first call 5:43."
Continuity mistake: When Nick "attacks" the kidnapper in the interrogation room, a single tear falls down from the boy's left eye. When the shot changes to a different angle, the tear is coming down from his right eye.
Factual error: When Captain Brass is in the travel agency and talking to the woman who works there, they access the last bookings taken by the victim. 4 lines up from the bottom, "Bob R" seems to have booked a return trip to Paris in Germany, when in fact Paris is in France.
A Bullet Runs Through It (Part 2) - S6-E8
Revealing mistake: When the dead Cirque de Soleil investor guy (the one that bled out in Super Dave's body bags) is on the exam table, you can see him breathe twice, despite that his stomach and ribs are cut way open for Doc Robbins autopsy.
Audio problem: Warrick is examining the garage for evidence and sees a stack of crates of soda, he sees one has a bullet hole in it. He picks it up and shakes it, it rattles, demonstrating the bullet is still in the can. He pops the ring to open it and it hisses, despite the fact that the bullet hole in the side would have let the pressure out. They clearly used an unopened can to film the scene.
Visible crew/equipment: When Sofia and Brass arrive at the interrogation room where Dwight is, you can see a red tape mark on the floor outside the door which Louise Lombard promptly glances down at and makes a point of placing her left foot on it. This has nothing to do with the fact that the "Hard Crime" film crew are following them because they're only observing.
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.
