Other mistake: When it shows Keri's license it says it expires in 2003, but the episode takes place way after that year, considering Katrina had already happened.
Continuity mistake: The unidentified subject is cutting a piece of flesh with a fork and a knife. The first shot shows him holding the fork with his left hand. His elbow is up, index finger straight, resting on the back near the head of the fork, the other four fingers wrapped around the handle. Next shot shows him elbow down, holding the fork with all his fingers wrapped around the handle.
Factual error: In the scene where the two unsubs are in the restaurant choosing the next victim, the family they are watching is a Hispanic family that breaks from speaking English for two lines to speak in Spanish. The father asks where the daughter is going, and she answers, "A lavar mis manos," which means to wash my hands. This is incorrect. In Spanish, you would say this as "A lavarme las manos."
Continuity mistake: Before the BAU catches the serial killer Carl Arnold, they used a heat sensor and it shows five people sitting at a table. They said there were three adults and two kids, but when they break in the house, the mother and one kid were sitting at the table, the father was tied up nearby, and Carl Arnold and the other child were in the basement. They were found by Derek Morgan right before Carl Arnold threw the child at Gideon, who fortunately caught him.
Plot hole: In the scene where The Reaper/George Foyet calls Haley from Marshall Kassmeyer's home he identifies himself as Victor Collins from the Marshall Service. Later in the episode Hotch calls Haley and tells her he needs Jack working the case. Jack comes to the phone and asks him "Is George a bad guy?" Until Hotch called Haley she didn't know Foyet was not a US Marshall named Victor Collins.
Suggested correction: He didn't say George.
Character mistake: At the end of the episode, Rossi quotes Anne of Green Gables author Lucy Maud Montgomery, but accidentally calls her "Lucille".
Continuity mistake: When Morgan gets off the phone after talking with Garcia about the list of chemicals he found, the hand holding the phone to his ear changes between shots. (00:13:55)
Continuity mistake: At the start, JJ puts a file down on the desk, and her left hand is in front of her, and she has 2 items in her right hand. When the camera angle changes to behind JJ, her left hand is now on her hip. (00:02:20)
Continuity mistake: When Reid disarms Maggie, he has his hand on the gun but no thumb on the hammer. When the shot changes to Maggie's POV, he has his thumb on the hammer. (00:37:20)
Revealing mistake: When the suspect is first put in handcuffs at the house, it's clear to see he is just holding the one cuff rather than wearing it. (00:27:50)
Continuity mistake: When Reid tells Lila that her manager is dead, he has his hands on the back of his neck. When the shot changes, his arms are now lowered and under the water. (00:27:00)
Continuity mistake: When Lila gets the note that was taped to her door, she holds it by the side in the close-up showing the contents of the letter and from the top when she is crumpling it up. (00:15:30)
Visible crew/equipment: When the suspect first enters the house, their helmet reflects all the camera and filming equipment. (00:04:20)

Protection - S10-E22
Continuity mistake: When JJ picks up Lizette Castro in her car to take her to her son, JJ gets Lizette to confess about the man in the pictures. We see JJ stop the car outside In the Dark by some trees before a flashback plays. After the flashback, it looks like the car is in some sort of parking house. (00:14:16 - 00:15:16)
A Real Rain - S1-E17
Factual error: When BAU walks up the stairs on the way into the courthouse the first time, the John Ferraro building in Los Angeles is visible in the background. They are walking up the stairs toward Los Angeles City Hall. The episode takes place in New York.
Other mistake: During the flashbacks, they show Prentiss with the rest of the BAU, but Prentiss didn't join until season two. If it was accurate it would've shown Elle, not Prentiss. (00:19:49 - 00:21:01)
Visible crew/equipment: During the plane interior scene after the opening credits as JJ is walking around handing out documents to the team, you can see a gap in the lighting outside and a crew member's face peeking out from behind the white walls. (00:04:00)
