Through the Looking Glass - S5-E19
Other mistake: Danny supposedly handcuffs an at-risk teenager. When the police officer takes her away to a cell, the girl isn't handcuffed. The handcuffs are just in her hands behind her back. (00:52:00)

Chapter Sixty-Eight: Quiz Show - S4-E11
Other mistake: Archie's uncle Frank tells Archie during an argument with him that he is 40 years old, with seven years in combat while in the military. But in a previous episode when explaining why he let Fred take the blame for his DUI, he claimed that he was a Desert Storm veteran in between tours at the time. Either the show got the wars wrong and meant to say he was an Operation Enduring Freedom or Iraqi Freedom veteran (no actual veteran uses "Desert Storm" when referring to combat in the Middle East after 9/11) or they're saying that he was only 10-11 years old when he went to Desert Storm. (00:29:30)

Other mistake: When we first see the Saito Gemu HQ, the shot is mirrored. It is apparent by the reversed company logo sign. (00:14:25)

Hard Bargain - S1-E9
Other mistake: When one of the kidnappers knocks on Michael's door, it shows him undoing a sliding barrel bolt before opening it, but the bolt does not have anything it slides into on the door frame rendering it pointless, especially as the door opens inwards. (00:30:20)

Log 51: A Jumper, Code 2 - S1-E19
Other mistake: Halfway through the show, the officers walk across the street to talk to some young toughs. The school sign painted on the street is spelled "Schol".

Other mistake: The URL seen on Siobhan's laptop (https://internet-search.comm7986/index.html) is obviously a fake URL.

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.

Other mistake: Dr. Wade is the ME for Jefferson Parish. Most of the victims are found in Orleans Parish. Not her jurisdiction.

Other mistake: When Cobb starts to chase the red Dodge, there's a shot of him passing between two vehicles (and very distinct buildings in the background). When Murphy picks up the chase, this same shot is reused, showing her passing between the same two vehicles.

Cold Murdering Bastards - S3-E2
Other mistake: When we see the Royal Gazette, with the misinformation about Washington's death, the 2nd column is repeated in the 4th column.

Home for the Holidays - S11-E1
Other mistake: Only one set of prints were said to be on the garrote but in the last episode of season 10 Graham handles the garrote before handing it over to the murderer without wearing gloves. So there should have been 2 sets of prints.

The Case of the Sausalito Sunrise - S9-E19
Other mistake: The owner of a Los Angeles trucking company tells a driver who is going to San Francisco, "Take the San Diego Freeway toward Bakersfield." That freeway runs from San Diego to San Fernando. It does not go toward Bakersfield.

Dedication - S1-E7
Other mistake: At about the 8 minute mark SnakeDoctor is talking on the radio to Bushmaster who is on the ground. There is a few seconds long shot where Bushmaster's earpiece is dangling wires and not connected to his Comms Gear on his vest. That earpiece can't be wireless.

Other mistake: Kim and Al chase the suspect into a wooded area. As Al is walking through the woods there is a puff of smoke from behind the the trees in front of him, but the suspect steps out from behind him.

What They Saw in Southie High - S1-E2
Other mistake: Agent Rohr asks who the cold case is related to. A dossier is given to him and the front cover contains a photograph and the name "Kanicki, K". Agent Rohr says "Kelly Kanicki" but there was no indication of the full name, just the initial. (00:08:30 - 00:09:00)

True Crime - S1-E1
Other mistake: When Tim Kono enters the lift, he presses floor 8, but gets off at floor 9.

Other mistake: In the newscast at the beginning of the episode, they incorrectly broadcast Robert Queen's birth date as 1948. They use the correct date in Episode 2 when it is shown as 1958 on his gravestone. (00:02:25)

Other mistake: When Lorne Malvo shoots out of the window the only thing sticking through the newspaper is the gun's barrel. When the shot changes to the scope view, you can see the outside. But you shouldn't be able to look outside.

Other mistake: When Michael walks into his office and sees Shawn, Michael is wearing a wedding ring. Looks like he forgot to take it off prior to shooting the scene. (01:00:00)

Other mistake: The shopkeeper hands Danny a Beretta 92fs/M9 handgun with a detached suppressor. To mount a suppressor to the muzzle end of the handgun the barrel needs to be threaded, and this one isn't. Sometimes barrels are threaded and when no suppressor is attached they are protected by a thread barrel cap to protect the threads from dings and bumps. There is no thread cap here either. (00:22:35)
