Go Fight City Hall -- To the Death! - S1-E1
Factual error: When Quincy, the well-experienced doctor, uses the defibrillator to bring a just deceased man back to life, he never put some gel on the paddles in the first place. (00:15:25)
Continuity mistake: When Lee tells Quincy what delicacies the Morenos have to offer on their boat she mentions 'German salami'. But in the German dubbed version and in the German subtitles she mentions "Hungarian salami". (00:20:25)
Continuity mistake: Lee states that she had won 1288 dollars when gambling - but in the German translated version and in the German subtitles it's 1284 dollars. (00:12:10)
The Two Sides of Truth - S2-E5
Continuity mistake: When Sam is hugged by his female colleague Alice something breaks in his breast pocket and there is a big spot of blood on his white coat. But the front side of Alice's coat is totally clean - not a single spot. (00:06:40)
Hit and Run at Danny's - S2-E6
Plot hole: There are three mistakes in one scene when Quincy talks to the driver of the hit and run car and he finds seatbelt bruises on the right side of the throat under an arm sling. First mistake: The bruises will hurt a lot and won't heal if they are under a sling. Second mistake: At the beginning, when the driver struggles with the kidnapped lady while driving he has no seat belt on which touches his throat. Third mistake: When you put a seat belt on sitting in the driver seat the belt will surely touch the left sight of your throat - not the right. (00:39:05)
Revealing mistake: In the arcade the killer talks to his helper while playing a pinball machine. He plays very agitated and strongly. But if you look closer at the below end of the playfield you see that there is no ball and the flippers aren't moving. (00:23:50 - 00:24:48)
