Blood Money - S10-E8
Visible crew/equipment: During the court case when Hamilton Stewart is taking the stand and answering to McCoy you can see the white screen in the reflection of his glasses very clearly.
Visible crew/equipment: After Dr. Murphy walks back in the operating room, there is a man with a boom microphone headset and paper against the right wall. (00:01:40)
Factual error: Detective Nina Cassady (who was introduced towards the end of Season 17) frequently wears casual tops that show far too much cleavage for a police officer on duty. If she showed up for duty dressed like that she would be sent home to change.
Det. Lennie Briscoe: Even though you are a taxpayer, you know, we don't actually work for you personally.
Question: What is a mistrial?
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.
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.
