Factual error: During the scene when Megan and the FBI are making the house entry, a scene cuts to two FBI agents, one with a M4 and another with a MP5. The agent with the MP5 has the magazine in his weapon installed backwards. (00:05:10)
Other mistake: The MP5 carried by one of the Federal officers breaching the meth lab has the magazine facing backwards.
Factual error: In one episode, there is a chase with the suspect driving an ambulance. The chase ends when the ambulance runs into and flips over a motionless taxi perpendicular to it, killing the suspect. There's no way this could happen, because at those speeds the impact would make the taxi flip over if anything.
Continuity mistake: Season 2 - Episode 16 - "Protest": Near the end when the guy is threatening to drop the nitroglycerin, he drops the test-tube and it lands on a red mat. However, when the agent picks it up, there isn't a mat anywhere near the test-tube.
All's Fair - S2-E18
Revealing mistake: In the scene where Don and the FBI crew is investigating the body of the Iranian victim, a split second closeup on the head of the Iranian woman shows she is breathing even though she's been dead for an hour already. (00:04:00)
Revealing mistake: When Crystal sets fire to the meth lab, she flings her lighter in a straight direction towards the front door. But you can see that the fire does not start there: it starts in the middle of the front porch, more than three feet from where her lighter landed.
Continuity mistake: When the FBI goes to arrest Tabakien, his men try to stop them and Don slams one of the guys' heads into a plate. The plate breaks into several pieces spreading the food all over. After you see the other men being stopped, you see a shot of the first guy again. And you can see that the plate is mostly intact and the food is not spread around as much.
Continuity mistake: Around the middle of the episode, Charlie Eppes and Mildred French are discussing in front of a board. She completes an equation and he adds a minus. In the next close shots, the minus disappears and reappears with angle changes. After three or four changes, a circle appears around the minus.
Continuity mistake: When Charlie is in his office talking to Larry, while going over the potential killers and victims, he writes the word "Killers" on the board and circles it. Then, when Charlie notices that Larry has left and says "gone", the writing is different. The 'k' is wider, and most noticeably, the left side of the circle is gone, and the loop in his 's' disappears. Once Charlie goes back to working, the word changes back to how it was originally written. (00:38:20)
Revealing mistake: Davis, the psychiatrist, is the second man to be killed. Although he was shot at five times, only the first two wounds, which are the highest, give blood, while the lower and later three do not.
Killer Chat - S3-E11
Continuity mistake: While Charlie is talking to Dr. York on the phone, the camera is at a wide shot, notice that Larry's name tag is not behind Amita on the wall. When the camera cuts to single shot of Amita, Larry's name tag appears on the wall. Then, the camera cuts to a wide shot again, and the name tag disappears. (00:38:25)
Continuity mistake: When the two police officers visit the dirty lawyer's place, they find him dead on his bed. In the first shot, there's a pillow next to his left shoulder. In another shot, the pillow is right next to his head.
Continuity mistake: When Amita talks to Charlie that she isn't quitting the running of curriculum and he's writing something on the board- he is holding a laptop entering something in it, than camera shows Amita and when it comes back to Charlie- there is nothing on the laptop screen (only black screen). (00:37:10)
Other mistake: In the opening sequence, Colby tells Helm at the airplane crash site that all of the passenger bodies have been moved to the L.A. Coroner's Office. However, later in the scene, there are shrouded bodies on the ground outside the command center tent.
Continuity mistake: "The Art of Reckoning": At the end when Lucy and Pony are at the table, she extends her left hand and he lays his head on her hand. In the next shot, he is holding her right hand with his head up and then in the next shot he is back to lying on her left hand.
Continuity mistake: When Bell is in the car with the female assassin, she pulls out a gun and points it at him. The camera then goes to an outside shot, where you can see the car's side window is already splattered with blood, before we hear the shot and the window shatters.
Magic Show - S5-E6
Continuity mistake: When David is outside the club being interviewed by the media, he comments that "We're in the middle of an investigation." However, when the statement is later played during news coverage, David noticeably stammers and says "we're" twice.
