Character mistake: Alvin Olinsky appears in this episode investigating the bombings in which Trudy was involved, but he died at the end of season 5.
Suggested correction: Where do you see Alvin (or even the actor Elias Koteas) in the scene? I couldn't see him in this episode.
Other mistake: S12 E2 Blood Bleeds Blue - Dante drives by the Green Line Morgan station stairs. It's the same stop Voight drives by as the stairs to the Green Line Kedzie station. The views are from a slightly different angle, but both station stops have a bike, a green scooter, the same weed growth, and a blue recycling bin in the same positions. (00:44:49 - 00:47:08)
Climbing Into Bed; You Never Know Who's Who - S3-E5
Factual error: S3/E6: You Never Know Who's Who - Lindsey is searching a dark house with her weapon and flashlight. Her hands are in the wrong position. Her hand with the weapon should be above her hand with the flashlight, because if she fires her weapon the slide will hit her hand with the flashlight and jam or injure her hand. (00:04:48)
Factual error: Adam is shot, and Kim responds to give him aid. Kim has her firearm out, searching and asking Adam, "where is he?" Instead of holstering her firearm, she tossed it aside to help Adam. Her action is not in accordance with law enforcement training. (00:36:17)
The Song of Gregory Williams Yates - S3-E13
Other mistake: Lindsay is video calling on Nellie's mom's phone to Yates. Bought at the scene of a fire, tells Finn to text Lindsay and let her know about the fire. We see the text come in, but it's on Nellie's mom's phone, not Erin's. (00:31:00)
Continuity mistake: Opening sequence, they are called to Kinzie and Dearborn. They instead show up at Franklin and Erie. After a short run down an alley, they call in their location as 3233 S. Princeton (more than three miles south of where they were, and nowhere near the Loop). (00:01:34 - 00:02:50)
A Night Owl - S3-E14
Continuity mistake: When the woman came into the precinct and showed Erin and Voight her daughter was taken on her phone, she dropped her hand after Erin took it. The very next shot from the reverse still shows her holding the phone as does Erin.
Other mistake: Upton needs sugar and asks Attwater if he wants some. Despite the fact that he says yes, she heads to the vending machine and buys one candy bar.
Factual error: Kevin sleeps overnight at woman's apartment. He doesn't share that he's a cop. The next morning in his unmarked police vehicle he uses his handheld radio that was appeared to be stored in the console and shows up on a violent scene with his weapon. It's obvious that Kevin used his official vehicle for personal reasons, and stored his radio and weapon in the vehicle unprotected overnight, which every police officer knows is wrong and a violation. (00:03:53 - 00:04:29)
Factual error: When Detective Olinsky calls out a license plate to Detective Upton he uses the wrong police phonetic alphabet. He uses the word Andy for A instead of "Adam", as is used by Chicago police. (00:35:00)
