Continuity mistake: When Horatio and Delko are on the dock talking to the blond about "Diablo" on the close up shots you can see that there is a large yacht parked at the dock she is sitting on. When the camera switches to the shots from behind looking over the pool with her at the far end, the yacht is gone.Boobra
Revealing mistake: The compound Heptan-2-one is mentioned several times in this episode. The actress concerned persists in pronouncing the last syllable 'one' as in the number 1, whereas its correct scientific pronounciation should be as in the word 'bone' ie. sounds like 'own'. Nitpicking certainly, but a dead giveaway to any viewer with a basic knowledge of chemistry.
Factual error: Calleigh Duquesne frequently wears completely inappropriate clothing throughout the whole series. She often wears blouses that are so low cut that the neckline is below the lower curve of her breasts. No officer of the court in the US would be allowed to dress this way. There is no grey area here, and this is not a character mistake - first time a CSI turned up at work dressed like that, she'd be sent home to change. Second time, she'd be on suspension until she agreed to change her dress standards. Also (and this regularly happens in CSI:NY as well) she is regularly wearing high heels - also a certain no-no for as CSI.
Other mistake: In episode "Kill Switch" it states that Jason Billings died from a broken neck, it shows Tony Decker kicking him in the face snapping his neck. Jason then tries to claw his way up onto Tony's deck leaving the scratches and blood and getting the splinter under his nail. This wouldn't have been possible since he would have already been dead.Boobra
Factual error: In the episode originally aired on 10/24/05 entitled 'Under Suspicion'Walter Dresden's DNA was positively linked to a murder in Orlando. Even if the judge dismissed the case against him in Miami, he would have been transported to Orlando to stand trial for that crime, not simply released.Boobra
Continuity mistake: The scissors are being profiled but as seen with last scissor coming in, it's discarded after only one cut of the tape. This is NOT conclusive, as the whole blade of the scissor has to be profiled, which means he has to cut the tape at least a few times, until he has covered the whole blade, section by section
Factual error: When Nikki is found dead, electrocuted in her bath by having a tanning lamp thrown into the water with her, the lamp is shown as being on, fully lit, and mysterious blue electric lights are playing about around it. However, when the CSI crew enter the room they note that the safety on the plug tripped instantly - 'just not in time'. There should have been no power to the lamp, then.
Factual error: As the firemen are putting out the fire, the water heater explodes, becoming a flying projectile. But you can see that the pilot light is still lit. The fire department would have immediately had all the gas to the home turned off, and the pilot would have gone out.Boobra
Factual error: Every time the investigators deal with IP-addresses, the addresses on display are impossible. Each of the four parts of an IP-address has to be between 0 and 255. This isn't equivalent to the movie-specific 555 area code for phone numbers - having an IP address outside that range is like having a phone number which includes the % symbol - it's just impossible.Christoph Galuschka
Factual error: Using a Draeger tube to test for nitric acid fume, the instrument made a clicking sound. This device does not click. The bellows pump is squeezed drawing air through the tube. A reaction takes place between the air contaminant and the material in the tube causing a color change. The length of stain is proportional to the concentration.
Factual error: I-131 (or any radioactive material) "at the end of its half life" does not instantly become non-radioactive, as was depicted in this episode. Radioactive decay is a continuous process; the half-life has no "beginning", but tells you how much time after "now" for however much is there at any time "now" to be reduced to one half that amount. Wait enough half-lives and the amount will fall to an inconsequential amount, but one is never enough
