The Collar - S12-E11
Visible crew/equipment: While the DAs are talking about their options in the case, after they first talk to the Priest and he refuses to testify, there is a few close ups of Nora's face. In most of these close ups the reflection of set lights are visible in her glasses.
Executioner - S18-E9
Factual error: Yost attacks and kills an innocent man, believing him to be Dr. Horace Garrison, a physician who administered a faulty lethal injection to a condemned prisoner, reducing him to a vegetative state rather than killing him. The problem is, medical doctors never, ever participate in an execution except to certify death, a legal requirement. They do not, ever, take an active role in killing the condemned person.
Det. Lennie Briscoe: You know, if I didn't already know you don't have kids, I'd know you don't have kids.
Trivia: Both Jerry Orbach (Det. Lennie Briscoe) and S. Epatha Merkerson (Lt. Van Buren) played guest roles before joining the cast. Orbach played a lawyer in the episode "The Wages of Love" in season two, and Merkerson played the mother of a victim in "Mushrooms" in the first season.
Question: What is a mistrial?
Answer: A courtroom trial that has been terminated prior to its normal conclusion. A mistrial has no legal effect and is considered an invalid or nugatory trial. This often happens when there is a lack of Jurisdiction, an incorrect jury selection or, as seen in many of the episodes, a hung jury, i.e. some jury members finding the defendant guilty while the other members of the jury will find the defendant not guilty and all jury members won't change their decision.
Answer: I was once a juror on a trial where the defendant started crying and talking about how his son would suffer if he went to jail. The judge became furious, decided that he had prejudiced the state's case (we were now thinking of his family, rather than if he were actually guilty), and declared a mistrial.
Answer: In short, any time a trial ends and is declared void before the jury delivers a verdict or a judge issues a decision. Generally a mistrial is caused by a jury not being able to come to unanimous decision or the prosecution does something that would make the trial unfair to the defendant.
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.
