Visible crew/equipment: After Peter storms into Ruth's office angry about the "Foot in Mouth Disease" headline, a short time later, Eli walks in just in time to see Ruth explain that Peter is actually in second place and climbing. When Peter hugs Ruth and compliments her strategy, Eli walks out of the office, and we can see the orange T-mark on the carpet behind him. (00:15:10)
The Debate - S6-E12
Visible crew/equipment: After Alicia and Frank have begun their mini debate in the kitchen, the hotel employee enters the kitchen; then, as Alicia says, "The system needs to be tweaked, not overhauled," the camera rounds the corner, and we can see a red T-mark and a red tape marker on the floor. (00:23:30)
Visible crew/equipment: At the end of the episode, when Alicia is listening to the audio recording on her laptop in bed, you can see the hand of a crewmember on the corner of the white cupboard at the left side of the screen. (00:42:45)
Factual error: The U.S. Customs and Border Protection officers are wearing ties with tie clips. Real officers wear a badge tie tack. (00:01:35)
Other mistake: Regarding the suicide of Karen Anderson, her boyfriend explains that Karen hadn't been studying with him because she wanted to be in the sun all day, but all the footage of the bridge she jumped from shows it to have been a mostly overcast, gray day. The first shot of the bridge is at the very beginning of the episode and is repeated several times throughout.
Continuity mistake: In the scene in the courtroom towards the end where Alicia is talking to the security guard who is in the witness stand, he glances over at the jurors. When they cut back to the jurors a few seconds later, they are wearing different coloured shirts. (00:33:30)
