Delko for the Defense - S8-E11
Other mistake: Horatio: "Eric, the forensics expert cannot get cold feet." There was absolutely no reason for Eric to be nervous. IF he'd been a CSI all this time, he would be in court testifying about his evidence on a regular basis. CSIs ARE the forensics experts.
Revealing mistake: When Phoenix bursts into flames on stage during her concert, the burn proof suit the stunt person is wearing (dressed as Phoenix) can be seen (her legs are very thick and her knees have deep wrinkles as well as the suit hem at her ankles can be seen).
In the Wind - S8-E14
Continuity mistake: When Horatio leaves Dr. Bradstone's cell, after informing him that his wife was having an affair, Bradstone's arms change position back and forth from across his stomach to behind his head. (00:34:25)
Miami, We Have a Problem - S8-E15
Factual error: Ryan is stated to have a BS in organic chemistry, working on his Masters in Genetics when we first meet him. When Travers tells him the shuttle was leaking oxygen, Ryan corrects him and says "air", to which Travers has to correct him. ANY gen chem student learns that "air" is a mixture of oxygen, nitrogen, water, and a few other trace gases such as helium and methane. This is a pretty big blunder for someone who supposedly holds advanced degrees in Organic Chemistry and Genetics.
Other mistake: When Boa Vista and Wolfe find the blotch of red marker ink under the tape from the bat it's a solid big red blotch, they determine it was transfer from the killer's hand. Then they show Cody holding the bat and he only has a small red smear on his hand, not even close to the amount needed to leave that kind of stain on the tape.
Factual error: After Horatio shoots out a window in the lab everyone starts waking up immediately, it would take much longer than one second for the gas to leave that size of a room and the people's systems.
See no Evil - S9-E3
Continuity mistake: In the beginning the kidnapper has a large build, like a football player, but later when he's in the van with the girl his build is much smaller.
Character mistake: Natalia professes not to know why the Statue of Liberty is green. The hue is the result of the natural oxidation of the statue's copper skin, a chemical reaction it's impossible to believe the crime lab's resident expert in chemistry doesn't know.
Plot hole: The whole scenario is fake and everyone at the bar is an actor, so why would they call the real cops.
Suggested correction: To specifically get the cops involved so Neal feels more in danger. LIVE Corporation basically filed a false police report, which Wendy Colton said the cops can talk to the company's lawyers about.
Other mistake: The hotel manager is charged with negligent homicide because he was using propane without the additive, but the victim was knocked unconscious. The additive wouldn't have made a difference.
By the Book - S10-E6
Deliberate mistake: When the CSI team reported to the island to find the dead body hanging upside down, they kept repeating how the body had been completely drained of blood. Yet, every time they showed the body, the jugular vein distention was very obvious. This could only occur in a live body or one still full of blood. Not a blow your socks off type of error but one very noticeable by anyone in the medical profession.
Factual error: There is no way the gun in this episode would work, the bullet world be moving way to fast for the shooter to accurately control the bullet to the target.
