Called Home - S18-E1
Character mistake: Michael Cutter decides to charge Bill Nolan with second-degree manslaughter, and tells Green and Lupo to pick him up. In the next scene, as he and Ed lead Nolan away in cuffs, Lupo says he's under arrest for murder.
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: I'm trying to decide what to arrest you for - obstruction of justice, harboring a fugitive or just being a general pain in the ass.
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: 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.
