The Prodigal Son (1 & 2) - S2-E1
Factual error: When Crockett takes out the hitmen in the nightclub, he fires 13 shots from his Detonics CombatMaster without reloading, when it has a maximum capacity of 6.
A Ghost for Scotland Yard - S2-E8
Factual error: Bearing in mind the episode takes place in London, Sir Arthur MacCready is driving his Rolls Royce. The car has the steering wheel on the left hand side. A true British Rolls Royce would have the steering wheel on the right side. This is a Hollywood Rolls Royce.
The Hoodlum - S4-E1
Factual error: Diamond's car phone, quite a rarity in the 1950s, attracts a lot of attention. But the car should have a huge antenna attached to make the gadget work (it doesn't), and Diamond would not be getting direct calls - they'd have to go through a mobile operator first.
Closely Watched Planes - S4-E3
Factual error: If there really was a hatch leading into mid-air in the airplane bathroom, instead of being soundless like shown, it would be incredibly loud and Max would have noticed. Also, the sudden pressure change would have sucked him out no matter what he did to stop it.
Factual error: When Tara goes into her office there's dried blood on the carpet from her faked miscarriage. Considering it's a bio hazard that happened days ago it would've been cleaned up and sanitized since it's a hospital.
Suggested correction: The blood is on carpet which is very difficult to clean as it's such an absorbent material. The carpet will keep the stain, but as long as it has been thoroughly sanitised there is no issue here. Yes, the carpet could have been replaced, but hospitals don't generally keep spare carpets laying about. Plus the fact that her office isn't a treatment area, there isn't much of a hazard anyway.
Doctor's office with a blood stain on the carpet? Highly unlikely.
Highly unlikely doesn't make it a mistake.
Factual error: At the beginning of the episode, Patrick Swayze is looking at photos of two Iraq veterans who have been murdered. He identifies one as a Marine Lance Corporal and the other as an Army PFC, but both pictures show men in U.S. Army uniforms. A bit later, his partner, who is supposed to be a Marine vet, refers to his decision not to "re-up," using the Army term for re-enlistment, rather than "ship over," as it's referred to in the Navy and Marines.
Factual error: When the stolen freight train is braking, the air pipe becomes disconnected. This should trigger the brakes on the train, but the train keeps going with no brakes. When the train is being slowed with no brakes working, why are there sparks coming from all wheels on the train? (00:32:00 - 00:38:00)
Episode One - S2-E1
Factual error: During this episode, Vincent is remanded to prison for suspected murder. At one scene he is seen working on the wing. Remand prisoners are not expected or allowed to carry out work duties in British Prisons.
Factual error: When Walter Goggins fires a LAW at the church from next to the vehicle, the back-blast from the rocket would have shattered the car's windows, and flying glass fragments would likely have injured the occupant. The show depicts neither outcome.
The Girlfriend Experience - S3-E8
Factual error: The group set up a sting for prostitution/solicitation, even though it isn't illegal in Canada. The unnamed city they patrol is Canadian, established in the "sister cities" they name, plus often referring to Rochester and New York as "across the border. As for prostitution, the only two times its illegal for adults in Canada is public solicitation (street walking) which doesn't apply for websites, or in running bawdy (cat) houses, neither of which apply here.
The Secret of the Unicorn: Part 1 - S1-E3
Factual error: The man selling the Unicorn tells Tintin that he can have it for 25 dollars. Tintin is Belgian and this is in his home town; they should be using francs in that time period. (00:03:30)
One Watson, One Holmes - S3-E19
Factual error: In the scene in the hospital, the guy who drove his motorbike into a van has an IV canula in his right hand, but the IV pole and the IV bag are on the left side of the bed, which means the IV line has to be long enough to go up to the bedhead, then behind the bedhead and then up to the bag, leaving no way to check for air bubbles.
Factual error: Throughout the series and credits, the ranks of Detective Superintendent and Detective Chief Superintendent are abbreviated as DSU and DCSU instead of the correct DSI and DCS.
Factual error: When asked about a trial Sebastian Berger replies that there was a jury verdict on a trial that took place in Germany. Germany has no jury based court system.
Factual error: In the scene where Bonnie gives Clyde the unloaded pistol through the jail bars, that gun was not manufactured until after 1972. It is a Bauer .25 ACP semi-automatic stainless steel pistol. Bonnie and Clyde's reign of lawlessness ranged from 1931 to 1934.
Factual error: When Susan is sorting Ruth's things, she finds Gordon's iPhone wrapped in a newspaper from 1994 with her voice-mail to him and realizes he went back in time, where Ruth killed him and took the phone from his corpse. Even if the phone had been turned off, after 16 years idle, the battery would have died long ago, but we see the phone is on with her message waiting. (00:55:50 - 00:56:45)
Factual error: 19 1/2 minutes in. They pull over a car and run the plate. Malloy tells the driver the car is registered to a Volkswagen. He should have said the plate is registered.
The Countess - S1-E4
Factual error: Two cops (the bowtie guy that cuffs Rockford and the one that watches him being taken away from his trailer) report to HQ saying that the protagonist is a suspect for a 157, to which Rockford reacts saying he did not murder anyone (and it is in fact what he is accused of). But homicide is in CA police code 187, not 157. A 157 is an entirely different felony. (00:21:00)
Factual error: A number of times throughout the season they refer to LSD being found in dead bodies and LSD being matched with other LSD found in other (living or dead) bodies. LSD starts a chain reaction in the brain which requires about an hour to take a noticeable effect. And, by that time, it has completely broken down and no longer exists as LSD in the body - before the person even begins to get high. There is no test for LSD even in the most bombed living individual, let alone a dead body years later.
