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)
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.
