Other mistake: In the opening scene, something catches the husband's eye through a window. He asks his wife to take a look and she gets scared. There is a dead body. When Lenny and Curtis arrive, and are lead back to the body, you can see the view from the street is obstructed. There is a display case, a pedestal, a vase and finally a wall. The head of the body wouldn't have been visible from the street and there was no other disturbance to catch someones attention: The husband and wife couldn't have seen anything.

1 mistake in season 7 - chronological order
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: 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.
