Humiliation - S6-E7
Other mistake: At the opening, the two undercover vice police are cruising down the street when the passenger cop looks to the side and says, "What the hell! Stop! Go back!" He saw something odd in the alley. When he says, "What the hell!" you can see through his window that the police car is about dead center of the building. His view of the alley where the victim was found would have been obstructed from view. They didn't move backwards, so it wasn't the alley they passed. The cop was looking into the alley they were approaching.
