Factual error: ACC Pat Gallan wears the ribbon of the Queen Elizabeth II Diamond Jubilee Medal. The medal was issued in 2012. Her medals would be correct for 2017 when the series was made, but not 2007 when it is set.
Factual error: At the end when Skeksis enters the crystal chamber, in the overhead shot you can see 22 arcane symbols around the crystal when there should only be 18, one for each exiled skeksis. (00:45:53)
The Murder's in the Mail - S1-E6
Factual error: Dead blonde guy is sitting upright in the chair, as Dave/Maddie close in, and Maddie realises he isn't moving. David goes to him and smacks him across the shoulder, to "wake him up" and blonde dead guy, right on cue, instantly slumps over a table at his right side, when the direction that David hit his shoulder, should have sent the dead guy slumping more forward, then at the front edge of the table. Obviously staged for the actor's comfort.
Factual error: When Jane is putting up the lost poster, the number to call is 1-800-saw-him. However, this is only a 6-digit phone number when it needs to be 7-digits (not including the 1-800 part).
Factual error: When Rich and Laura are searching for drug information from the 1960s, they visit the US Patent Office website; under the heading "SSRIs", is displayed "Selecttive Serotonin Reuptake Inhibitors" - with the double-t spelling error. (00:15:25)
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.
Family Day - S2-E5
Factual error: The phone number Harry is given has an exchange that starts with "0" (the first 3 digits after the area code). Phone numbers (in the US) can't start with "0" since that's the "operator."
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)
Factual error: The chopper's main rotors are at a speed enough to cause rotor wash, but the men's coats or hair don't move at all, when they should have been buffeted around.
Factual error: The only person ever addressed as "Sir" is the brigadier, and then only occasionally. No other officers ever seem to be addressed in this way.
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: 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.
Factual error: The FBI agent introduces himself and says "Mike Weston - I did my thesis on Joe Carol at the academy." FBI agents are required to have a university degree, but they don't write thesis' at the academy. A person is either in a university or at Quantico getting trained. They are not writing papers at Quantico. They need the degree beforehand to get in. (00:10:30 - 00:11:30)
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.
Episode #1.1 - S1-E1
Factual error: The series is set in 1933, as the initial captions show. Yet the locomotive pulling the Orient Express is a JNR Class C58: the C58 series was built starting from 1938 (C58 239 used here is from 1940).
Factual error: The Commissioner of the Metropolitan Police has red fabric within the crowns on his rank insignia. This would be correct for most British police forces, but the Metropolitan Police uses blue fabric instead.
Chapter Seventy-Nine: Graduation - S5-E3
Factual error: Archie revealed that he joined the Army to avoid repeating his senior year and was shipping to Basic Combat Training the following morning. Before leaving he would need to wait for his background and medical checks to be completed (including getting his dropped murder charge reviewed for suitability), which could take weeks. Also, the Army usually requires a diploma or GED to ship to basic. There were brief periods when the Army was accepting dropouts but it was not when this episode took place.
The Alchemy Murder Case File 3 - S1-E8
Factual error: The Latin text on the supposedly old tome (which is written with a modern font) displays an alchemist diagram. It is a reproduction of a famous drawing meant to portray the Philosopher Stone in the Sylva Philosophorum, but whoever copied it does not know Latin, because certain words are misspelled ("Merceralia" instead of "Mercurialia", "Humides" instead of "Humidus"). (00:10:10)
Factual error: When the cops need to arrest a medical professional, they are frequently shown barging into his/her office, exam room, or even operating room. This would never happen in real life and is strictly forbidden, as it is a gross violation of the patient's privacy, and in the case of the OR, could contaminate the sterile environment, thereby jeopardizing patient safety as well.
Los Moscos - S2-E1
Factual error: Outside the church headquarters where Norman has his stroke is a board saying 'United Methodist Church'. The UMC didn't come into existence until 1968. It was the Methodist Episcopal Church in the 1930s.
