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: DI Renton is a Metropolitan Police officer 'parachuted' into Kent to solve a big case. This hasn't happened for many decades. Local police forces investigate their own crimes without help from the Met.
Boundaries - S4-E3
Continuity mistake: Alex and his mom are talking with Grandma about masturbation. Alex is in his school uniform shirt but for one shot he has a hoodie on, then in the next shot it's gone.
Factual error: The Navy Seals call in air support and provide a fire mission to given coordinates. The targets are engaged with rockets and gatling/chain guns. The UH-60 Black Hawk is shown leaving after the air strike. This UH-60 however only had mini-guns in the doors. The type of UH-60 needed for this action would be the UH-60 DAP, which is configured as a gunship and has no troop carrying capacity. The DAP can carry chain guns, mini-guns, missiles and or rockets. (00:03:00 - 00:03:23)
The Gang Tries to Serve a Subpoena - S4-E2
Continuity mistake: Luca and party are about to board a green private jet. Moments later when they take off, the shot shows the forward underside of a white plane. At first I thought that maybe it was white on the underside, but the nose wheel well doors are indeed green, and the takeoff picture shows an airplane with white nose wheel doors. (00:19:40)
Episode #1.5 - S1-E5
Factual error: The senior police officer's name tag reads "Assistant Commissioner" but he wears the rank insignia of a Deputy Assistant Commissioner.
The Buffer - S1-E3
Continuity mistake: When Mickey touches Trish's boob, her hand is over the grey shirt, in the next shot, her hand in inside the grey shirt, and over the grey shirt again in the next shot.
Factual error: Major Markham is consistently referred to as the CO (Commanding Officer). As a company commander, he is actually the OC (Officer Commanding). In the British Army, CO is a title reserved for the commanders of battalion-sized units.
Continuity mistake: Near the end of the episode when Nico is burning the photo of her father, she burns it at the top left corner in a close-up shot. Then in the following shot the photo is suddenly burning at the top right corner instead.
Pompeii's Gate to Hell - S4-E8
Factual error: This episode includes a segment about an abandoned dry dock in San Francisco. At one point, one of the commentators several times refers to the U.S.S. Ward as a "battleship," and marvels that it was built in 17 days. The Ward (DD-139) was a 1200-ton destroyer, not a battleship, and was launched after only 17 days, but then took another two months to complete. By way of comparison, the California (BB-44), an actual battleship of 32,000-tons built during the same time period, too nearly five years to complete.
Factual error: The provincial police is always described as the Ontario Police Department (OPD) instead of the correct Ontario Provincial Police (OPP).
Episode #1.1 - S1-E1
Continuity mistake: The protagonist finally receives the Anmitsu, breaking his orgasmic trepidation. In the close-up, the tray is really close to the teacup, but in the following shot it's definitely further away, to the point that Kantaro in facts moves it to the right, in the same position shown in the close-up. (00:12:15)
Deliberate mistake: The police force in the town is the Gendarmerie, the standard issued firearm is the Sig Sauer P2022 in 9mm. The police officers on this show carry a Beretta and not the 9x19mm one which is the model 92fs, they carry a never issued Beretta 84 chambered in .32 acp or 9mm short. Plus they use some weird holster where the gun arches out and hangs low like a cowboy holster and dangles around. Easy for a suspect to gain control of the officers gun and this happened in this episode.
Character mistake: One of the characters, Agent L, is usually talking to the kids via some gadget with bad audio. In The Golden Gauntlet, the first time she appears on the screen she misnames Agent J, calling him "Agent G." She then later in her speech calls him by his name correctly.
Continuity mistake: When Dr. Andrews tells Mrs. Cross via video chat that her husband has blood in his NG tube, the clock in the top left corner of Mrs. Cross' phone says 5:09. Two shots later, it has suddenly changed to 5:01. A few moments later it changes to 5:10, then back to 5:01 and then for some reason to 4:53 at the end of the scene.
King of Camp - S1-E5
Continuity mistake: When Andy and Deegs begin eating the hot peppers, Deegs starts by biting into half of one pepper, leaving half of the pepper remaining, but in the next shot, he is suddenly holding a whole pepper, with no signs of it being eaten.
Factual error: Two women come into town somewhere around San Luis Valley, Colorado with ring-necked Pheasants. The pheasants were brought into US a few times (East coast, CA) but really did not get established until late 1880s and in Colorado likely in the late 1890s (eastern and southwestern). The problem is it supposedly depicts the year 1880. They would more likely may have found some Gunnisons Sage-Grouse nearby or rabbits. (00:16:10)
Episode #1.3 - S1-E3
Factual error: Billy is called up into a specific unit of the Royal Artillery. This didn't happen. He would first have been sent to a Royal Artillery training depot and only after training would he have been assigned to a unit.
