Episode #1.6 - S1-E6
Continuity mistake: Sami takes Maya directly from the location where Tommy Dark's body is found to his home, but Maya's outfit is completely different when they arrive.
Plot hole: When Nicky goes into prison in Mexico to give a criminal a shot of insulin, two errors are seen. 1) The needle and syringe are far too big for an insulin shot, which takes a one ml syringe and a small sub-cutaneous needle. 2) When we first see the syringe, there is a small amount of insulin in it, but it grows the more times we see it, until a large syringe is two-thirds full - insulin is enough in a one ml syringe.
Near Death Experience - S12-E1
Revealing mistake: At the end Jack wrestles the knife out of the attacker's hand and in doing so cuts his own hand. However in the extreme close up you can see the rubber knife is bending when Jack wrestles it away. (01:30:30)
Visible crew/equipment: After Hutch finds the ticking box with the clown and Starsky's badge inside, when it cuts to Hutch and Dobey walking toward the squad room, the cameraman and camera are reflected on the door's glass window. (00:17:20)
Continuity mistake: When Buzz and Provenza race out of the squad room to follow Rusty in the frantic search for Stroh, Buzz is in shirt sleeves with no tie. However when they arrive at their destination Buzz is wearing a coat and tie.
The Secret Fate of All Life - S1-E5
Continuity mistake: The first time we see Detective Cohle being interviewed by the other two detectives, two of the beer cans on the table in front of him completely vanish between shots when he asks to see the rest of the discovery file.
Continuity mistake: Tony Sparkle is seen defacing a picture of Judy Talent. He starts writing something beginning with T. The action cuts away for a moment, and then back again. The words on the picture are "SAD OLD BAT". (00:07:05)
Revealing mistake: When the thief places The Blue Carbuncle in the goose's throat, it's obvious he actually doesn't put the gem in the bird's mouth. He pretends to, but then drops the gem into his other hand. This is all visible in the shot.
Visible crew/equipment: As Joe approaches the third car with the bad guy in it, there is an unknown man, possibly a crew member, reflected in the back window where there wasn't a man before.
Continuity mistake: In S:1 Ep.10 Maddie says she'll be 15 in a week. Season 2 picks up 6 months later. In S2ep5 Bosch uses Maddie's birthday to access a computer. Password is 01/10/01. This makes the date sometime in July of 2016. Then in S2ep6 George Irving is killed, and the end of watch broadcast lists his date of death as 7/24/2015. This error is reinforced in S2ep10 when they show a plaque being mounted to honor George.
True Crime - S1-E1
Other mistake: When Tim Kono enters the lift, he presses floor 8, but gets off at floor 9.
Other mistake: Dr. Wade is the ME for Jefferson Parish. Most of the victims are found in Orleans Parish. Not her jurisdiction.
Continuity mistake: The assassin is running across the square with the poisonous needle in his left hand in several shots. But moments later, when tackled to the ground, it is pressured from his closed right hand.
Other mistake: When Cobb starts to chase the red Dodge, there's a shot of him passing between two vehicles (and very distinct buildings in the background). When Murphy picks up the chase, this same shot is reused, showing her passing between the same two vehicles.
Borealis 301 - S1-E5
Continuity mistake: Near the end, Tom takes out the cipher key that was previously written on. But the cipher key used in the close up shots is different than the original. The words are spaced out and crossed out differently.
The Legend of Curtis Ballard - S2-E3
Factual error: In the first flashback scene of Ballard serving a Mormon mission in Lithuania, he laments that he has been on his mission for 18 months and has yet to baptize a single person. In a later flashback scene when he and his companion are visiting the prostitutes, he states that he and his companion are 19 years old and they should be in college, going to parties, getting drunk, getting laid, etc. Instead of serving missions. These scenes take place in 1991, at which time young men did not serve missions for the Mormon church until after they turned 19, so if Ballard had already been on his mission for 18 months, then he should have been at least 20 years old, and closely approaching 21.
Character mistake: When the bodyguards enter elevators, they always enter last; they should be entering first to ensure it is secure. This is particularly visible in the hotel where the elevator can stop on any floor and Special Protection Branch does not have complete control of it as an express.
Episode #1.4 - S1-E4
Revealing mistake: The tabloid story with the plight of the Latimers just came out, and various characters are looking at it. In the bit when David Tennant tosses on the desk his copy of the Herald, the second paragraph of the second column goes "Sitting in the family home, surrounded by pictures and mementos of Danny" etc. It is the same text that was at the very beginning of the article when the store owner was looking at it. The newspaper is a prop with the same text in a loop. (00:35:00 - 00:36:30)
El traje del tío Jacinto - S2-E16
Visible crew/equipment: In the credits, there's a unknown person hiding behind Don Ramón (Raymond).
