CSI: Crime Scene Investigation

Overload - S2-E3

Factual error: Several problems surround the electrocution death and the investigation. First, there is the insinuation that the boots should have protected the victim from the electrocution because of the rubber soles. Regular shoes and standard work boots will not protect anyone from electric shock. You are still grounded. You have to wear special electrician's boots to insulate you from electric shock. These boots cost about triple standard work boots. Second, the CSI crew found a nail embedded in the boot. They theorized that is how the boots were grounded out. The problem there is the nail had to be pushed all the way through the sole and through the insole for it to work (the close up of the boot showed the nail in all the way). Even if the nail was barely through the insole, the victim would have felt the nail poking him at every step. With the nail all the way through, he wouldn't have even walked two steps before puncturing his foot on the nail. Third, there is the nail itself. When Grissom is examining the boots trying to find why they failed (failed to prevent the electrocution), he poses the question "What is the most common item found during construction?" The answer is a nail, and the nail in the boot appears to be a roofing nail. The construction site is for a multi-story prison. Nails aren't used in the construction of multi-story urban buildings: concrete and steel are. Carpenters come in after the building is erected and work on the interior, but the are no roofing nails.

Overload - S2-E3

Factual error: In the episode where the worker got electrocuted in a construction site the main character, before replaying the victim's fall, says that "terminal velocity is 9.8 seconds squared". What he should have said was that acceleration due to gravity is 9.8 meters per second squared.

Overload - S2-E3

Factual error: Grissom sets up a little experiment to see if the deceased's blood is conductive to electricity. All are amazed when the blood does conduct electricity. All blood is naturally conductive. As a matter of fact, cardiac output is measured as a function of blood conductivity.

Bully for You - S2-E4

Factual error: In the scene where Grissom is talking to the coroner about the bully who was shot, they talk about how the bully had "Dextrocardia" which is why all his organs are a mirror image of normality e.g. heart on right and liver on left. In actual fact Dextrocardia is only when the heart is on the right rather than left, the actual condition Grissom should have said was "Situs Inversus" not "Dextrocardia."

Overload - S2-E3

Factual error: When they are explaining why a nail was hammered into the electrocuted workman's boot, it is said that cars are protected from lightning strikes because they are insulated from the ground by their tires. Actually, tires conduct electricity, because they contain carbon (see: http://cartalk.cars.com/Columns/Archive/1994/November/11.html). Cars are actually protected from lightning by the Faraday Cage effect, which is explained on http://www.physics.gla.ac.uk/~kskeldon/PubSci/exhibits/E3/. Not a mistake CSI scientists would make.

Ellie - S2-E10

Factual error: The treasury officer stated that the couple was from "Las Vegas County". Anyone from the government (local/county/state/federal) should know Las Vegas is in 'Clark County'. Sara (who works for LVMPD/Clark County) did not react at all.

Chasing the Bus - S2-E18

Factual error: The CSI crew set up an experiment. They put some chloroform into the tire, set the bus on a dynamometer (or some other testing platform) and wait for the tire to fail. The tire fails in the experiment in the exact same amount of time as it did in real life. Problem: They have no idea how much chloroform was used and it would be impossible to match it by luck. More chloroform used would equal quicker failure. Then, there is the heat. The tire traveling over the hot asphalt road would build heat faster then on their testing platform. More heat would mean a quicker failure, too.

Chasing the Bus - S2-E18

Factual error: Sara calculates the time needed to sabotage the tire at a minute to a minute and a half. That is, remove the valve core, allow the majority of the air to escape (cannot pour anything into the tire while the air is escaping) pour in enough chloroform to sabotage the tire, replace the valve core, and air the tire to pressure. Even with an industrial air compressor, it would take over 2 minutes to air that tire to full pressure.

And Then There Were None - S2-E9

Factual error: Ballistics expert Bobby Dawson mispronounces the word "Koch" in the term "Heckler and Koch". He pronounces it "kotch" instead of the correct, "koch" (rhyming with lock0. A ballistics expert would know the correct way.
