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.
Suggested correction: I'm not sure where you're getting your information, but medical doctors are involved in lethal injections more than just certifying death. This is why so many groups were actively trying to stop the practice of medical profession involvement. In 2007, 17 states required physician involvement, which included doctors at times having to administer the injection.

The botched execution took place in South Carolina, which absolutely forbids medical practitioners to take an active role in killing a condemned prisoner. In fact, they are considering switching executing prisoners by firing squad instead of lethal injection, at least partly to distance medical professionals from the actual procedure leading to a person's death.
