CSI: Crime Scene Investigation (2000) - 13 mistakes in whole show

Deliberate "mistake": Every time the investigators deal with IP-addresses, the addresses on display are impossible. Each of the four parts of an IP-address has to be between 0 and 255. As they do have to use IP-addresses some time, they could use addresses starting with 10. Those would be real addresses although not used as an official IP-address. This isn't the same as phone numbers using 555 - any IP address over 255 just wouldn't work. It would be like mentioning a phone number which uses the symbol for pi.

Continuity: Series 7 - Part 1: When Sara and Warrick are at the table discussing the case, Sara's box containing her veggie sandwich changes position depending on whether the camera is looking at her or Warrick. (It moves from directly in front of Sara, and then several inches to her right toward the edge of the table).

Other: In episode "The Good, the Bad and the Dominatrix" When the son goes to the bank he tells the manager that there was a million dollars in that account last week, there was 843,508.00 taken out leaving a balance of 31,053.86. That only adds up to 874,561.86. Not a million dollars. He doesn't say close to a million dollars He says there was a million dollars in that account.

Continuity: In episode 8-1 Dead Doll: When Warick finds the zip-tie in the trunk it is not looped, when he holds it up for Grissom it is looped. He would not have looped it himself.

Other: Season 10, episode 4 "Coup De Grace": When Nick is doing the phenolphthalein test on the q-tip, it turns pink immediately and starts to overflow pink coloring all the way down the side of the stick, which is not how that test works. Normally it takes a few seconds and only turns color around where the blood is.

Continuity: Season 10, episode 3 "Working Stiffs": The picture of the employees holding a sign at work with the X's thru them at Paulie's house changes between two completely different photos when far away vs. up close.

Factual error: Season 9, Episode 9 - 19, "Down": Towards the end of the episode they are searching along railroad tracks. A MetroLink train passes by. MetroLink serves the greater Los Angeles area, but does not serve Las Vegas.

Plot hole: Series 9 episode 12: "Agent Hartford" had no fingerprints: the FBI "removed" them. But when they find the street piece that Vinny had, they dust it and say that Hartford's prints were all over it. This might be OK, if he were a real agent on the books (but they never heard of him at Quantico), or if he were a real criminal - but in that case, they would have sussed it all out earlier.

Continuity: Season 9, episode 3 "Art Imitates Life": When J. Skaggs is being interrogated by Brass he has his hands on his lap. In the next shot they are both on the table.

Plot hole: Episode 9-18, "Turn, Turn Turn": Greg states that the dead motel manager crawled up into the ceiling the same way that he did, and you see Nick open the access panel in the ceiling. The manager couldn't have closed the ceiling panel after him and no one was managing the hotel in the week he was missing. The panel should have been open when Nick came into the room. The new manager stated he didn't know if there was a panel in that room, since he just got there.

Continuity: In Episode 8-08, "You Kill Me," when Archie takes the first kilo of cocaine out of the case, he takes the bottom-most left-most kilo. When he takes out the second kilo, he removes the same package with the empty space being two to the left of the one he would have removed.

Plot hole: Lizzie had the car towed to icebox canyon. When you see her watching the car being lowered onto Sara, there is no tow truck there, there is no sound of any machinery lowering the car, and when the shot pans back there is nothing there that would have helped her move the car. She is not strong enough to hold up a car, put an unconscious person under it while holding it up, and then lower it without some kind of winch.

Continuity: In the Season 8 episode "Goodbye & Good Luck," near the beginning, Sara and Warrick bump into each other and Warrick drops his medicine. During their conversation, Warrick squeezes Sara's shoulder and then drops his hand. The shot instantly cuts to a view from behind Sara and Warrick's hand is back on her shoulder with no time (or reason) for him to have put it back.
