Plot hole: The CSIs catch a murder suspect putting down a drink can when reviewing security footage of a robbery, and immediately realise they didn't see it at the scene so assume one of the first cops on the scene must have removed it. Thing is though, the murderers shot out the security camera before the actual shooting occurred, meaning there was loads of time off-camera for the killers to take the can with them, but the CSIs never even consider this - they jump to the conclusion a cop took it even though there's no actual evidence for that.

Factual error: Season 3, episode 49 (Not What It Looks Like). Breaking glass with sound is possible, but would not work as depicted in the episode. First, in order to break the glass, you have to force the glass to vibrate at its natural frequency - that is, the frequency at which it would vibrate if it were tapped. Each piece of glass has its own natural frequency, depending on a range of factors including size, chemical makeup, shape, hardness, and manufacturing methods. No single frequency would shatter all the glass in the store at the same time. Finally, in order to break the glass the piece has to be closed-ended. You can't shatter a plate of glass with sound (nowhere for the sound waves to resonate). Please see http://www.madsci.org/posts/archives/feb98/887203231.Ph.r.html

Factual error: Several police and crime lab personnel are in the train car looking at the dead girl and discussing the possibility that this death could be the result of a bio-hazard or chemical hazard. Later in the episode, ebola and anthrax were discussed. These are level 3/4 hazards which require Hazmat suits and oxygen supplies. At the very least, there should have been very serious access control to the scene. None of them are wearing any type of protective gear except rubber gloves, and there is nothing more than standard crime scene access control. Contrast this with a scene later in the same episode where 2 characters in the lab are wearing respirators when dealing with the dust and other stuff from vacuum cleaning system. If the CSI team or the police really suspected that there was a biohazard or dangerous chemical agent present at the crime scene, then their behaviour was quite cavalier under the circumstances.

Factual error: They state that the heart monitor on "Nicole" never showed any movement at all as she was being smothered, because the killer swapped it out and put it on herself. When Mrs. Rollins was smothering her daughter thinking it was Nicole, her heart rate would have raced and her blood pressure would have gone up a little as she strained to hold the bag over her face. The monitor would have picked that up.
Continuity mistake: In Episode "Happily Never After": In the opening when the CSI team is looking at the puncture wound of Fiona Chisolm, there is no blood coming from the wound. It is actually mentioned that there is no blood. Then it is determined that she was dead for about 6 hours, but now there is an L-shaped blood drip pattern to the chest wound.
Factual error: The plot is about a mosquito who stung the murderer. Although Gary Sinise mentions (correctly) that only female mosquitoes bite, the one caught alive on the table is a male mosquito (look at its bushy antennae and abdomen which is thin and definitely deflated). All mosquitoes used in the episode are male.
Audio problem: When Mac and co. enter the basement of the house in Queens (the one where the third woman was found) the record player lifts off its needle and moves to another spot on the record, cutting off the sound for a second. However, the music starts again slightly before the needle hits the record.
Continuity mistake: In Episode 4-03 You Only Die OnceIn the beginning of the episode when Flack calls in the address of the apartment he calls in the address of 260 W 72nd Street, however, when the burglar is shown repelling down the side of the building the address on the front of the building is 535.
Continuity mistake: Season 3, Episode 11 (Raising Shane) Just as Casey is caught we see Detective Flack tackle him to the ground. The moment before Danny jumps on top of Casey we see that he is lying on his side. Yet when the camera changes position he is lying on his front.
Plot hole: In episode "Silent Night": When the mother checks on the baby in the first scene, you see the killer knock over the snow globe. The mother wouldn't have heard it since she was deaf, but she would have felt the vibration on the hardwood floor from the heavy object hitting the floor.
Continuity mistake: Episode 19 - Personal Foul; Lindsay is going through the cheerleaders' photos to find a biometric match of the heavier woman, and she picks a head shot of a blond cheerleader. She removes it from the pile to scan it, seeing through the back, we can see what the actual picture looks like. It is a close up picture of a woman wearing big sunglasses. When the scan is complete, it is revealed as the original cheerleader photo.
Continuity mistake: Stella prints the pictures of 6 suspects. Mac takes them all, holds one up and says : "That's the man we're looking for." But only 5 pictures comes out of the printer - and the picture of the suspect isn't among them. Mac holds up the picture of an black guy with afro hairdo - the suspect is white with rumpled black hair. Where does his picture come from ?
Visible crew/equipment: Season 6, episode 7 "Hammer Down": Just after Mac and Ray have finished briefing the other officers as they are about to begin a chase, there is an actor's red T-mark on the floor, visible just as the officers begin to walk towards the scene.
Factual error: When Mac is held hostage until he can prove that the bank robber did not shoot the manager, he asks for a portable CT machine to be delivered. CT stands for computed tomography which is a machine that takes slice pictures of the body and puts them together to form a whole image. This is why a CT machine has a tube like quality to it, so it can take slice-like pictures around the body. When it arrives the machine is not a CT at all, but an ultrasound. This is made obvious when Mac uses the transducer probe (wand-like attachment) to scan the body. Anyone who has had any of these procedures done, or has seen them in TV shows, or knows how to search images on the internet can see the difference between these two very different machines.
Factual error: "The Thing About Heroes" When Mac has a flashback to an incident when he was 14 years old (in the 1970s) and gives the money to Bobby Toole the twenty-dollar bills all have the large 20 on the back side. This was not issued until 2004.
Continuity mistake: In autopsy, Mac, Stella and Dr. Hawkes M.E. are examining a skeleton that was found on a bus. As Mac asks about cause of death, Sheldon points to a skull fracture that is evident above the skeleton's left eye, a fracture that wasn't there when the skeleton was first discovered sitting in the back of the bus.
Factual error: Danny explains how the glass was broken using ultrasound waves to hit the glass at their resonant frequency. He explains it could be done using a mp3-file and a mp3-player. As mp3-players are designed for the human ear, the upper frequency limit is around 20 khz, far too low to produce a sound capable of shattering glass.

Plot hole: In Episode 4-4, "Times Up," it is stated that Kevin Murray will be killed at 9:45. When Mac is standing over the dead body, he looks at his watch. It is 9:45 and he says, "Right on time." Unless Mac was standing on the sidewalk when he flew out of the window, he actually would have died earlier, since it would have taken time for the police to be called and arrive on scene.
Revealing mistake: Season 5, episode 18 "Point of No Return": When Danny fires at the bad guy, there are sparks coming from the metal pipes when his bullets hit them. One of the things causing the sparks burns too slowly, taking over a second before it fades out.
Continuity mistake: An assistant shows Craig T Nelson and Gary Sinise a mockup of a New York Ledger news page, with a photo of an NYPD officer and a headline that reads: line 1 - "NY's", line 2 - "Finest take", line 3 - "A break". When Sinise takes the photo and puts it on the desk a few seconds later, the text layout is on 2 lines instead of 3.
Other mistake: Mac is leaving a message for Christine. There is a close up of his cell phone. The keypad on the phone has the numbers in the wrong order. On every phone in history the first row of numbers is "123". On Mac's phone it is "789", like a computer keyboard.
Factual error: When Mac is using the mouse to demonstrate induced hibernation to Peyton, the speed of the mouse's heartbeat on the heart monitor was about that of a human. Due to their small size, real mice have an average heartbeat of 500-600 bpm, which is so fast it can sound like humming.
Factual error: During the autopsy of the head, the shot changes to inside the eye, showing the needle entering to extract the vitreous fluid. The inside of the eyeball is shown as white. This is incorrect: the inner lining of the eye is black (hence why the pupil, a hole in the iris, looks black).
Plot hole: At the end of the episode, Stella and the others determine their rape suspect is guilty because they confirm the tree sap on his clothes transferred to the victim's underwear. That transfer should have been discovered, if not blatantly obvious, during their initial processing of evidence.

Factual error: All the victims were supposedly killed using thalium-201 - a radioactive isotope with a half-life of just 72 hours. e.g.: In the space of two months there would be 10 nanograms for every gram applied to the source of the radiation poisoning (i.e the book) - not enough to make Sid ill without making the perp very ill. He would have had a much higher dose than anyone infected.

Continuity mistake: At the beginning of the episode when Mac & Stella first look in the box at the beach, Lucas' head is at the back right corner of the box with a leg wedged from the back left to the back right corner and the back quite uppermost. When they open the box in the lab and go to remove it with the doctor, the head is in the front right corner with arms and legs visible uppermost like the body has been rotated, but it would not have been touched or removed from the box by that point. The second arrangement of the body is shown in the flashbacks throughout the episode.
Plot hole: The coroner found the ticket stub in the throat of the guy whose tongue was cut out, he died in the ER. The ER staff would have have found the ticket stub while trying to save his life. With the tongue being cut out they would have opened up his mouth to stop the bleeding.
Factual error: when Mac Taylor's ID card from the Marine Corps is being shown, there are two unintentional mistakes and one probably intentional. First, the design of the ID card in no way resembles an actual DoD issued military ID, but this was probably an intentional mistake by the creators of the show. The picture on the ID however, has two unintentional mistakes. First, Marines are never photographed in their dress blues for official purposes; Mac would have been in cammies or service dress charlies for the photograph. Second, Mac is revealed in several episodes to have been an officer, yet he is shown wearing the dress blues of an enlisted man.
Continuity mistake: when the bank manager's wife is being prepared for autopsy, Sid begins by taking pictures of the wife. In these shots you can see her wrists and ankles are bound with tape. First he cuts off the tape on the ankles and places it in the evidence envelope with Danny and Lindsay. Next he begins to cut the tape from the wrists. As he is doing so, the next shot cuts to a full body view of the wife in which she has the tape back on her ankles again.
Factual error: When they are looking at footage of the suspect leaving the crime scene they notice something in his sleeve and the computer generates an image of a steering wheel lock. There is no way they could come up with that from the outline in the suspect's clothes.
Deliberate mistake: Though the series title is technically inaccurate, since in New York CSIs are called CSUs (crime scene units), it's called "CSI: NY" to tie it in as existing in the same universe as its sister series "CSI: Crime Scene Investigation" and "CSI: Miami."

Continuity mistake: Mac is crouched down on the ground and removes a piece of paper from the grass next to the victim without a crime scene glove. He has a flashlight in the other hand with no glove either. The next shot shows him standing with gloves on both hands.
Plot hole: When Sid and Hawks are telling mac that the piece of glass from the girls shoulder is from the window from bar, Sid tells Mac the scar shows it healed in the last month, but it's been established several times earlier in the episode that the bar shooting happened 3 months earlier.
Other mistake: The body in the bank has one entry wound because the gun has no kickback, but in the flashback of the manager getting shot the shooter pushes the manager back then shoots him twice, the managers body moving alone would have causes the two bullets to enter at to different points.
Factual error: Towards the end, Eva Mason blows up Leonard Brooks' flat in an attempt to kill him, by heating up gas from the stove using an uncovered light bulb. This wouldn't work as shown as the filament from the bulb would burn out before igniting the gas - and besides, a spark from the light switch would have ignited it first.

Continuity mistake: The dead body of a girl is in the autopsy room. There is a closeup of her face on a TV monitor. Her hair is wet and tucked under her head and the v-shaped stitches on her torso are reddish in color. Next shot her hair is spread out and the stitches on her torso are blueish.
Character mistake: In the scene in which Stella, Adam, and Hawkes are trying to get clues from the $1 bill left by Shane Casey at the bar, Stella notes that the Latin phrase "E Pluribus Unum" has had its word order changed and now reads "E Unum Pluribus". From this, she deduces that the meaning has changed from 'from many, one" to "from one, many'. However, Latin is a highly inflected language, in which the meaning of a word changes not from its position in a sentence, but from the ending that is attached to the word. Therefore, both 'e pluribus unum' and 'e unum pluribus' mean exactly the same thing.
Continuity mistake: When Stella and Linsday are checking a table in Rob Mayer's home, when Stella is about to move the table, she has two gloves in hers hands (not wearing them, just holding). In the next shot, she is just holding one glove. And when the shot changes again, she is instantly wearing gloves on both hands.
Audio problem: Season 5, episode 17 "Green Piece": When Stella is typing on the Apple keyboard she hardly lifts her fingers from the keys, yet we hear a loud clicking sound. That type of keyboard doesn't make that kind of sound, unless you pound the keys with great force. Also, the clicking sounds don't match up with her keystrokes.
Continuity mistake: When Flack, Lindsay, and Stella go to Kim Wey Imports, it's bright daylight out. But when Flack chases Wey out of the warehouse, the sky has suddenly become pitch black. They were only inside for a few minutes, so it shouldn't have been that dark.
Audio problem: During the sequence where Lindsay is telling them about the tape with the lipstick on it, they show a man tying up a woman. You hear the sounds a woman would make if she was muffled by a gag (tape) on her mouth as she's being tied/struggling throughout the scene, but her mouth doesn't get taped until the end of the scene.
Plot hole: At the end of the episode, Adam and Stella are checking how many others there are bearing the same name in a government database. "Stella Bonasera" gives one result, being the Bonasera character. A search for "Sid Hammerback" also gives one result, a 90 year old woman (the characters say it has to be his mother). But Sid himself should have shown up too, with the search yielding two results, not just one.
Other mistake: Hawks is handed a pretty small container with some of the victims brains in it, and says there is about 50% of the brain still left out there to find. There is no way half of a brain is in that small container, it's not even filled all the way.
Other mistake: Danny & Hawkes see a customer list on a shopkeeper's computer. Computer issue: Not only can she print the list and bypass a print option popup window with a single keystroke (implausible), but there are no icons/links on the page for software to do anything with that list. As well, the window scrollbar shows that there are nearly two pages of content on that screen, yet it appears to be a single complete page for the camera. Technical issue: The list contains 27 customer names - but one is repeated (Ryan Jackson).Later in the episode, they cross-reference that customer list (then printed on an opaque board in Mac's office, with that same duplicated name), against a company's employee list on Lindsey's pad computer. She was "able to notice one last name in common," yet there are three last names on the employee list also on the customer list, and one of those last names has two people listed - so that's four people who could have connections, yet only one was checked.
Factual error: In the shot where Mac discovers Adam's details on the killer's desk, under Adam's name is what is supposed to be Adam's computer IP address. Although the first two octets 172.16 are a plausible address, within a private address range, the third octet is a little too high at 450 (the largest number in an octet is 255) and the fourth octet at over 1000, well.
Factual error: During their investigation, the CSIs learn that their murder suspect is in the witness protection program, under FBI protection. WITSEC falls under the jurisdiction of the United States Marshals Service, not the FBI. And considering how many protected witnesses the Marshals Service relocates each year, it's doubtful they would be shorthanded enough to need help from another agency to locate a missing witness.

Character mistake: As Peyton is examining the body and reporting her findings to Danny at the beginning of the episode, Mac picks up a credit card he deducts was used to open the door, but he isn't wearing gloves; this would compromise the evidence even if by holding it by the edges he preserved the prints.
Factual error: The episode has a character in it called Klaus Braun ("Braun" being the German word for "brown"). However, all of the characters pronounce his surname wrong, saying the "au" like the "or" in "bored", not the proper German pronunciation, which would in fact, be the same as the English meaning, "Brown". Other German character's names were pronounced correctly, and surely Klaus/Abraham would object to having his name pronounced incorrectly.
Revealing mistake: After Danny breaks the glass in the lab allegedly using sound waves, you can see in the shot immediately after the glass breaks, a thin green laser beam from roughly further top left to near bottom right. It's assumed this is what actually broke the glass.
Continuity mistake: In the coffee shop, Don & Mac are having breakfast; Raymond arrives, looks down at Mac's belt & sees his gun & badge beside each other on his right hip.A minute later, after Raymond leaves, Mac exits the coffee shop looking for Raymond; his badge has jumped to the opposite side of his belt.
