Other: 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.

Factual error: In episode "Burned," 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.

Factual error: Series 5, Episode 13 : "Shock". 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.

Continuity: In Episode 6-1 "Dangerous Son" - In the beginning when the suspect is running from the house he has his hood on, when he jumps off the roof and falls on the canopy he has no hood on, then when he gets up his hood is back on.

Continuity: In Episode 'You may now Kill the Bride', when Calligh and Ryan are in the lab discussing the diamond, Calligh takes her earring off, but when she says, "The molecular structure of carbon makes it one of the hardest surfaces on Earth", her earring is back on. Then she scratches the glass with the earring she took off.

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.

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.

Audio problem: In episode "Born to Kill" when Ryan and Natalia are talking about the ticket he gave the suspect, Natalia's mouth keeps moving long after the words stop being said.
