Chapter Two: The Weirdo on Maple Street - S1-E2
Factual error: When Chief Hopper and his fellow patrolman are standing over the lake, Hopper has a radio on his belt. The radio is a modern Motorola walkie talkie and at least a decade newer than it should be.
Factual error: The building shown between the stated times is located in Japan instead of the US/Washington DC as suggested by the actions in the scene. This is proven by by the Chinese characters In the Dark-gray concrete wall in the lower left side of the frame, as well as the red and blue colored circular road signs in the lower far right of the frame which are not in use in the US but in this combination unique to Japan. The street furniture, such as the road markings, the vegetation and the buildings also resemble Tokyo. (00:06:55)
Factual error: When Riggs and Murtaugh go to investigate the scene where the body of Ramon Alvarez is discovered Scorsese states that Alvarez's dog tags say "SEAL" on them. His dog tags would not say that he is a SEAL on them. The information listed on dog tags is as follows: Name, Social Security Number, Blood Type, Service Branch, and Religious Preference. There is no way to tell what a given service member's MOS (job) from his or her dog tags. (00:14:00)
Factual error: The show starts in 1901 with a woman constable working for the Metropolitan Police Service (Scotland Yard). However women didn't join the Metropolitan Police until 1919 (which is also when the first woman's police uniform was created). Prior to that, women volunteered in the Women's Police Service, but that wasn't formed until 1914.
Seeds + Permafrost + Feather - S3-E17
Factual error: Bozer and for that matter I would assume all of the team went to a spycraft academy. A basic subject in any of such academies is surveillance, including proper techniques to follow and stake out someone. Bozer being so inept at tracking MacGyver's father is inconceivable given their training.
Factual error: Captain Souter is shown lying dead in the snow following the massacre at Gandamak. In fact, Thomas Souter was one of the few who survived to be captured by the Afghans and was later freed.
Factual error: In the opening, a number of Lancaster bombers are flying over Windsor Castle, they did not come in to service until 1942. (00:00:20)
Factual error: "Underground" is set in 1857 Georgia, yet the padded baseball glove August Pullman gives to his son is of a type used during the early 20th century. Before 1883 when padded gloves were first manufactured, gloves were either not used by baseball players or railroad brakeman's gloves were used.
The Snowplow - S3-E3
Factual error: When Chidi activates the superboard, one of the items under Local News is "Rep. Sackett indicted on 231 counts of fraud." Lower house members aren't referred to as Representatives in Australia, the correct title would be MP. (00:09:13)
Factual error: A 3 series BMW from either 1979, 1980, or 1981 shows up in 1973 New York city. (00:32:15)
Trace Decay - S1-E8
Factual error: When the armed party comes into town to steal the safe in the bar, the leader points a repeating rifle at a victim on the ground and shoots. When he fires a used cartridge flies from the gun. Repeating rifles do not eject cartridges when they are fired. Automatic weapons eject a spent cartridge when fired. Repeating rifles only eject the cartridge when the lever is wrenched. (00:32:20)
Katie Girls - S3-E3
Factual error: Randall flies out last minute across the country to Los Angeles to be at his sister's side for her surgery. The scene where he arrives at the hospital and meets up with her husband Toby in The Waiting Room is prefaced by an exterior shot of the supposed hospital building. The sign outside the hospital indicates the name as "Sutter Health Alta Bates Summit Medical Center," which is a hospital in Berkeley - the San Francisco Bay Area - about 400 miles north of Los Angeles. (00:19:30)
Factual error: You can see the Unicredit Tower on the Milan skyline - the episode should be set in 1997 but the unicredit tower was built in 2012. (00:31:00)
Factual error: Pierre Bezukhov's spectacles are of the type with nose pads, which were not invented until the late 1920's.
Episode #1.2 - S1-E2
Factual error: The railway tickets just say "Kent to Greenwich" instead of specifying the actual station where they were bought as they would have done.
Factual error: Cars in Thailand drive on the left side of the road with the steering wheel on the right, unlike the ones shown in the episode.
Factual error: Almost all the people being shown skydiving have no experience doing it, but the instructor allows them to jump out of the plane unassisted after only giving a theoretic introduction into the subject. First time skydivers are always assisted in some fashion, usually through a tandem-jump or a parachute opened by a line attached to the plane.
Factual error: The judge requires £100,000 to be paid to the court in bail and Yvonne's husband later says he had to cash in bonds to get the money. In Britain, bail is not paid in advance. It is sufficient to prove that it is available if necessary and it is only required to be paid if the defendant later absconds.
Factual error: The Metropolitan Police isn't a national police force (except for close protection and anti-terrorist matters). It has no authority over other police forces. It doesn't take over criminal cases from other police forces. It hasn't even provided investigation teams on request for decades. Every force handles its own investigations. A Met chief superintendent and his team coming in, as depicted here, and taking over an Avon and Somerset investigation just wouldn't happen.
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. Prior to leaving he would need to wait for his background and medical checks to be completed (including getting a waiver for his dropped murder charge), which could take weeks. Also, the Army usually requires a diploma or GED to ship to basic. There were very brief periods of time the Army was accepting dropouts but it was not when this episode took place.
