Character mistake: When Faith arrives in LA she is carrying a bag. She puts it on the ground and then steals a man's jacket and wallet. Afterwards however, she leaves without picking up her bag.
Character mistake: Series 1, Episode 3: When Alex tells Ray she will re-trace his steps for clues linking to the murder of a girl, he says, "Don't worry, lads! Wonder Woman's here!" Alex replies, "FYI DI Carling." Ray is a DS, not a DI.
Character mistake: When Bree calls the police when she hears a noise downstairs, she says she lives at 4355 Wisteria Lane when her address is in fact 4354 Wisteria Lane. 4355 is the Scavo residence, not the Van De Kamp residence.
Character mistake: When Kate mentions James Bond, and DiNozzo lists the actors who have played him, he forgets Timothy Dalton. As a self-proclaimed film buff, that's not a mistake he would make.
Character mistake: At the end of April and the beginning of May in 2004, Luis was decoding the CDs with the Crane secrets on them. For an extended period of time, Luis left the CDs completely unattended at Hank's house. Luis told several different people that the computer was decoding the CDs and didn't need anybody there to do it. Given that Alistair is virtually omniscient in Harmony, it's ridiculous that he didn't break into Hank's apartment and take the CDs.
Character mistake: Scully continually addresses the senior police officer as "Captain." But he wears sergeant's stripes. As a law enforcement officer continually dealing with other law enforcement officers, Scully is not likely to make this mistake. More likely a failure to match script with costume.
The Battle of Central Park - S3-E6
Character mistake: When Justine Feraldo looks at the checkpoint feeds, she says that the Strigoi have overrun the checkpoint at 116th Street and 110th and Amsterdam. But the feed says 118th and Amsterdam.
Character mistake: When Ginnifer Goodwin leaves the supermarket to go the parking garage, the green sign says 1 hour parking Customer's Only. It should say Customers Only, without the apostrophe.
Character mistake: Elliot Stabler is interrogating a suspect and he says "Well maybe he got pissy because of the 2.2 you blew into the breathalyzer." He said two-point-two but he meant point-two-two because a 2.2 BAC is like 5 times the lethal limit, so a 0 .22 BAC makes more sense. (00:20:10)
Catch A Falling Star - May 21, 1979 - S2-E10
Character mistake: In the preview for this episode, Charlie has trouble getting his countdown straight. He shouts that Sam is on in 50 seconds, then 47, then 48. In the episode itself, the mistake is corrected with a rather obvious overdub, changing the final number to 43. (00:02:05)
Character mistake: The registration number of Alan Salt's car is HUA222B, but when Rachel is on the phone asking an officer to look up the car's registered owner she gives the registration number as B222HUA.
Character mistake: The firefighters state that the acronym for CPR is ABC for Airway, Breathing, Circulation. This is very outdated as in 2010 the American Heart Association changed the recommendation to CAB for Compressions, Airway, Breathing following evidence that compressions first in CPR saves more lives.
Character mistake: When Rose thinks Mickey is dead, she says she'll have to tell his mother. But in Rise of the Cybermen in Series 2, she says that Mickey's mother has been dead since he was a child. (00:30:17)
Character mistake: At the Roadhouse Cooper states that the second victim (Maddy) was found dead two days ago. It has been less than 24 hours since the body was found: he likely means she was murdered two days ago.
There's No Place Like Home - S28-E16
Character mistake: The old photo of Sylvia and her friend shows them in RAF uniform. Sam, who is a serving British Army officer and could be expected to recognise the very obvious differences between the uniforms, keeps referring to Sylvia being in the Army and Sylvia does not disagree with her.
Didn't We Meet at a Murder? - S4-E22
Character mistake: When Chin Ho reads Wellman's license plate number to the police dispatcher and repeats it to confirm, he recites a different number the second time. (00:30:05)
On the Run - S3-E13
Character mistake: When Mrs Haldane is giving her statement to Regan she tells him that Cook was wearing dark glasses when she saw him outside her neighbour's house, but Cook wasn't wearing any glasses.
Stop Me Before I Hug Again - S1-E13
Character mistake: In Brian's "Laws I Have Broken Since Joining FBI" list, item #30 misspells the word "recorded" - "30) Recoreded NFL Game Without Consent." He'd only have that knowledge if he was using NZT, and if he was, he wouldn't make a mistake like that.
Character mistake: Rodney says that one hour in real time would give them months inside the field. This is incorrect because if the ratio of time were 1:250 as stated before, one hour would only convert to 250 hours, which is 10 days and 10 hours.
Character mistake: Will's tax demonstration to his volunteer staffers is incorrect. He applies the various tax rates to the entirety of each salary range. The person who makes $150K and is in the 36% rate...in his example he has them paying 36% on their entire salary, not just the portion of it that puts them ahead of the next lower tax rate. If the tax rate jumped to 70% at income of $1M, and a person earned $1,050,000, they wouldn't be paying the 70% rate on all $1,050,000 of their income, only the last $50,000 of it. Will's example makes it look like they would be.
