Character mistake: A computer display of currency transactions shows the word "withdrawal" spelled as "withdrawl." (It is also spelled correctly higher up on the display). (00:25:05)
Character mistake: Tig gets bit on the right butt cheek. Tara tells Chibs to give him a local, which is a numbing injection so she can stitch him up. Problem is that Chibs does the injection in the left butt cheek. You are supposed to give the injection close to the wound to numb it before stitches.
Log 1: The Impossible Mission - S1-E1
Character mistake: They turn left onto Moorpark St and they say into the radio they are going east on Moorpark. However, the street sign shows they are going west. (00:10:30)
Character mistake: The sign in front of the tank Lt. Ladd is trapped in reads "ORDINANCE TESTING FIELD, DANGER.", but an ordinance is a type of decree or law. They probably meant 'ordnance', which is another word for artillery.
Hercule Poirot's Christmas - S6-E1
Character mistake: After Japp's arrival, when Poirot walks up the stairs with the two male detectives, at one point he says "Mais no madame." ("But no mylady.")
Character mistake: Det. Baldwin Jones calls ADA Valerie Haywood Teresa. (00:49:10)
Blood, Sweat, and Cheers - S4-E8
Character mistake: In the scene where Jack is phoning Col. Decker to give him the A-Team's location, the camera zooms to a wanted poster of the three members. The poster lists Faceman as the rank of Captain, instead of Lieutenant.
Character mistake: McCoy asks his witness, an expert geneticist, what the odds are that a DNA sample presented in evidence does not match that of the defendant. He answers "About one in two hundred." That is idiotic. If the DNA samples are identical the chances that the the sample presented in evidence does not come from the defendant is about one in two billion, not one in two hundred! A bright high school senior would know that, never mind an expert geneticist.
Suggested correction: If the odds are 1 in 200, that means the accuracy of the DNA is 99.5%. If the odds are 1 in 2 billion, that means the accuracy of the DNA is 99.9999999995%, which simply isn't true.
In fact as any geneticist (i.e, anyone like me) will tell you the chances of two identical DNA "fingerprints" coming from two different and unrelated individuals are around one in two thousand million. Two billion. In fact the odds are much higher than that but we scientists don't like to make claims that sound unlikely or fantastic. The accuracy of DNA fingerprinting is, as you point out, 99.9999999995%. You correction is wrong and the posting is correct.
Except that's not what happened in the scene or what happens in real life. You simply don't understand what you're arguing. You're not a geneticist.
Unto Others - S4-E7
Character mistake: When Cutty quits the truant officer job and walks out of the office, he runs into his old girl from way back. She calls him David instead of Dennis. (00:51:00)
Character mistake: The ship's doctor is sometimes addressed as "lieutenant surgeon" instead of the correct "surgeon lieutenant."
Character mistake: When Frank is starting to show Amy how to take the gun from him he removes the magazine and makes the statement "clip empty" - any Marine, certainly one as well trained as him would never refer to that as a "clip" - it is a magazine. A "clip" is a device intended to help rapidly load ammunition into a magazine.
Character mistake: When the private investigator shows Castle and Beckett the VIP Liaisons website, "Liaison" is misspelled "Liason." (00:17:40)
Character mistake: In the tent Djem reaches for food with his left hand. Totally a big no-no in the Arab and many other cultures! He would never lean on his right and leave his left arm - his unclean hand free.
Character mistake: At the Life Guard Trials, Kelly is the first Angel to arrive. She finishes 20th. Then, four other competitors arrive (21st / 22nd / 23rd / 24th). Then, Kris arrives. The judge says to her "You're 23." (00:11:15)
Character mistake: The FBI team responds to a murder crime scene. The victim is lying face down in the bed with blood everywhere. The team leader takes the victim's wrist with his bare ungloved hand. A trained FBI agent would never touch a murder victim without gloves - one to protect himself and two not to contaminate the crime scene. (00:10:00)
Character mistake: Ottawa is misspelled "Ottowa" on Nicholas Jenson Davis wanted picture.
Character mistake: In the opening scene, Sherlock makes a point to correct Barry's poor grammar. But later, when talking to Watson, Sherlock uses poor grammar by saying "who's sleeping with who." It should be "who's sleeping with whom." Not a mistake Sherlock would make.
Character mistake: After being asked in class, Max refers to what he does as a "vivisection of a once-living organism", which in itself is a contradiction because vivisections are performed on living organisms. What Max does is called dissection, or more specifically autopsy, because he does it to determine the cause of death.
The Hammer - S1-E10
Character mistake: Raylan Givens tells Judge Reardon that he carries a ".45 Glock" but this is untrue. Throughout the series with the exception of the beginning of the first episode Raylan Givens carries a Glock 17, which is only chambered in 9mm parabellum. His backup can be seen to be a Glock 26 which is also in 9mm.
