Factual error: Horatio and Detective Tripp refer to Redfish only being able to be caught in one place around Miami - "Mosquito Lagoon." First, Mosquito Lagoon is not in Miami, it is several hundred miles north, and secondly, there are plenty of places to catch Redfish around Miami. I used to live there. (00:12:30)
Factual error: When Horatio is responding to the prison transfer van flipping over, he calls officer down into his Nextel radio. After he finishes speaking, you hear the distinctive Nextel transmission beep from when you would begin a conversation /transmission. If he had been transmitting his call, it would not have beeped after he was done speaking, it would have beeped before. (00:28:00)
Factual error: During a interview, Tripp tells a suspect that he helped loosen the lug nuts on a police vehicle. However, when they flash to show the lug nuts being loosened, the actor is turning the lug wrench from left to right which would in fact tighten the lug nuts. (00:29:10)
Continuity mistake: The time sequence in the beginning is very screwy. The victim and her friend are partying inside and it is dark outside. The streetlights go out and the inside lights in the building go off. As the girls come out of the building, it is daytime. Seconds go by, then it is midday. As the girls talk to Mr. Biker/Murderer in the close-ups, the sun is in front of them and their butts are in the shade. In the zoom-out shots, their butts are in the direct sunshine.
Factual error: (Episode: Sun Block) At the beginning of the episode, all the pool patrons are watching an eclipse, the sky darkens and they watch as the moon passes in front of the sun. The process, from the moon first beginning to touch the sun's disc to total eclipse occurs in approximately one minute. It is impossible for an eclipse to happen that quickly; it would take at least an hour to complete the process shown.
Continuity mistake: 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 mistake: When Candace walks onto the pool deck Luke hugs her but he does not touch her face. When they play back the feed from his sunglass-camera. he does.
Inside Out - S6-E3
Continuity mistake: When Natalia is talking to Wolfe in the lab, Natalia is leaning on a table on her arms, then stands up straight. In the next shot, she's leaning on the table again and stands up a second time. (00:21:20)
Plot hole: Delko is rummaging in Speedle's locker. Why would Speedle still have a locker, considering he's been dead 3 years? Even if they couldn't allocate it to someone else, why are his personal effects (e.g. his wallet) still in there? Shouldn't these have been returned to his family?
You May Now Kill the Bride - S6-E14
Continuity mistake: When Calleigh and Ryan are in the lab discussing the diamond, Calleigh 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.
All In (2) - S6-E16
Continuity mistake: The body is discovered by two teens fishing with explosives and an arm comes up in the water. When they pull out the body that was inside a car, the victim has both arms tied up to the wheel and at the morgue she is missing one arm. We can even see the doctor cut the tape off the wheel and the victim's wrist to expecting to find prints on the inside of the tape.
Factual error: When the show begins, a man is run down by a Dodge Charger. The man's injured leg apparently cuts a bio-diesel line under the car. The Charger never was a diesel, and probably never will be. Further proof is at the show opening which showcases a very low-tone exhaust rumble which can only be a gasoline V8.
Continuity mistake: At the beginning of the episode, we see the red car falling entirely into the hole, none of the parts are out of it, but, a few shots after the CSI team has arrived, the back of the car is now out of the hole. (00:02:15)
Factual error: In Natalia Boa Vista's backstory, she states she knew Horatio from her "work with the FBI." But not all FBI agents started as LEOs (law enforcement officers). In her whole time as a CSI, she wields a badge, makes arrests, and interrogates suspects just like a cop (the ONLY 3 characters we know for certain that were LEOs were Calleigh [the flashback episode with Horatio and Jesse], Eric [the flashback episode when Horatio tells Eric to "come see me when you finish the academy"], and Ryan Wolfe, who's fresh off beat patrol when he joins CSIs). In this episode she tells Calleigh she's late to her crime scene because she just picked up her new sidearm and "now I can back you up on crime scenes!" BUT, if she were already a cop she would have been issued a firearm upon graduation. Thus, Natalia (and Walter) were never cops. This show took severe liberties with reality. Real CSIs are no more than expert witnesses, NEVER given the responsibility of arresting or interrogating suspects.
Rock and a Hard Place - S6-E19
Continuity mistake: When Alexx talks to Delko in the lab about her son, Delko's hands are resting on the fuming machine in front of him, then instantly on the table top. (00:29:05)
Continuity mistake: During the intro of the episode. Trent/Roger is hanging in the gazebo, and the M.E. is examining the body. In one shot Calleigh is talking to the party thrower and as you look over his shoulder you see the back of the M.E. examining the mouth of the man and the front of the dead body. Next shot you see M.E. examining the mouth again. Next shot the hung dead body is turned almost with his back to Calleigh, with M.E. still examining the body around its shoulders. Next shot the body has turned again and is facing Calleigh. (00:02:00)
Continuity mistake: When Eric and Natalia determine that their murder weapon is the top from one of the limo's alcohol bottles, the angle of the top in Delko's hands changes between shots, without him actually moving. (00:07:30)
Dude, Where's My Groom? - S8-E6
Visible crew/equipment: Horatio's body doubles face is seen for a split second during the helicopter landing, he has the wrong hair and nose to be Horatio. (00:41:15)
Bone Voyage - S8-E7
Continuity mistake: When Horatio notices the Band-Aid on Nathan Cole's finger, and Dr. Ray asks if they can get a warrant, Horatio's position changes between shots from facing Ray directly then has rotated position about 90° and is looking at Ray over his shoulder. (00:29:35)
Plot hole: The mother lets her daughter drive because she forgot her glasses inside the restaurant and cannot see to drive. This only makes sense as a means to move the plot forward because if she was still at the restaurant (which she would've had to be because she couldn't have driven elsewhere without her glasses) then she would've just gone back in to get them rather than let a 14 year old drive.
